Here is, I. The institution of the sabbatical year, Exo 23:10, Exo 23:11. Every seventh year the land was to rest; they must not plough nor sow it at the beginning of the year, and then they could not expect any great harvest at the end of the year: but what the earth did produce of itself should be eaten from hand to mouth, and not laid up. Now this was designed, 1. To show what a plentiful land that was into which God was bringing them - that so numerous a people could have rich maintenance out of the produce of so small a country, without foreign trade, and yet could spare the increase of every seventh year. 2. To remind them of their dependence upon God their great landlord, and their obligation to use the fruit of their land as he should direct. Thus he would try their obedience in a matter that nearly touched their interest. Afterwards we find that their disobedience to this command was a forfeiture of the promises, Ch2 36:21. 3. To teach them a confidence in the divine Providence, while they did their duty - that, as the sixth day's manna served for two day's meat, so the sixth year's increase should serve for two years' subsistence. Thus they must learn not to take thought for their life, Mat 6:25. If we are prudent and diligent in our affairs, we may trust Providence to furnish us with the bread of the day in its day.

II.The repetition of the law of the fourth commandment concerning the weekly sabbath, Exo 23:12. Even in the year of rest they must not think that the sabbath day was laid in common with the other days, but, even that year, it must be religiously observed; yet thus some have endeavoured to take away the observance of the sabbath, by pretending that every day must be a sabbath day.

III.All manner of respect to the gods of the heathen is here strictly forbidden, Exo 23:13. A general caution is prefixed to this, which has reference to all these precepts: In all things that I have said unto you, be circumspect. We are in danger of missing our way on the right hand and on the left, and it is at our peril if we do; therefore we have need to look about us. A man may ruin himself through mere carelessness, but he cannot save himself without great care and circumspection: particularly, since idolatry was a sin which they were much addicted to, and would be greatly tempted to, they must endeavour to blot out the remembrance of the gods of the heathen, and must disuse and forget all their superstitious forms of speech, and never mention them but with detestation. In Christian schools and academies (for it is in vain to think of reforming the play-houses), it were to be wished that the names and stories of the heathen deities, or demons rather, were not so commonly and familiarly used as they are, even with intimations of respect, and sometimes with forms of invocation. Surely we have not so learned Christ.

IV.Their solemn religious attendance on God in the place which he should choose is here strictly required, Exo 23:14-17. 1. Thrice a year all their males must come together in a holy convocation, that they might the better know and love one another, and keep up their communion as a dignified and peculiar people. 2. They must come together before the Lord (Exo 23:17) to present themselves before him, looking towards the place where his honour dwelt, and to pay their homage to him as their great Lord, from and under whom they held all their enjoyments. 3. They must feast together before the Lord, eating and drinking together, in token of their joy in God and their grateful sense of his goodness to them; for a feast is made for laughter, Ecc 10:19. O what a good Master do we serve, who has made it our duty to rejoice before him, who feasts his servants when they are in waiting! Never let religion be called a melancholy thing, when its solemn services are solemn feasts. 4. They must not appear before God empty, Exo 23:15. Some free-will offering or other they must bring, in token of their respect and gratitude to their great benefactor; and, as they were not allowed to come empty-handed, so we must not come to worship God empty-hearted; our souls must be filled with grace, with pious and devout affections, holy desires towards him, and dedications of ourselves to him, for with such sacrifices God is well-pleased. 5. The passover, pentecost, and feast of tabernacles, in spring, summer, and autumn, were the three times appointed for their attendance: not in winter, because travelling was then uncomfortable; not in the midst of their harvest, because then they were otherwise employed; so that they had no reason to say that he made them to serve with an offering, or wearied them with incense.

V.Some particular directions are here given about the three feasts, though not so fully as afterwards. 1. As to the passover, it was not to be offered with leavened bread, for at that feast all leaven was to be cast out, nor was the fat of it to remain until the morning, lest it should become offensive, Exo 23:18. 2. At the feast of pentecost, when they were to begin their harvest, they must bring the first of their first-fruits to God, by the pious presenting of which the whole harvest was sanctified, Exo 23:19. 3. At the feast of ingathering, as it is called (Exo 23:16), they must give God thanks for the harvest-mercies they had received, and must depend upon him for the next harvest, and must not think to receive benefit by that superstitious usage of some of the Gentiles, who, it is said, at the end of their harvest, seethed a kid in its dam's milk, and sprinkled that milk-pottage, in a magical way, upon their gardens and fields, to make them more fruitful next year. But Israel must abhor such foolish customs.

All thy males - Old men, sick men, male idiots, and male children under thirteen years of age, excepted; for so the Jewish doctors understand this command.

The first of the first fruits of thy land,.... Both of the barley and wheat harvest, and of the wine and oil; yea, Jarchi says, the seventh year was obliged to first fruits; and Josephus (d) relates, that the Jews were so tenacious of this law, that even in the famine in the time of Claudius Caesar, the first fruits were brought to the temple, and were not meddled with:

thou shall bring into the house of the Lord thy God; to the tabernacle, during the standing of that, and the temple when that was built; which were the perquisites of the priests who officiated in the house and service of God: so Pliny says (e) of the ancient Romans, that they tasted not of the new fruits or wines before the first fruits were offered to the priests, which seems to have been borrowed from hence:

thou shalt not seethe a kid in his mother's milk: and so a calf, or a lamb (f), as Jarchi interprets it; which some understand of slaying a young kid and its dam together, and so is a law against cruelty, like that law of not taking the dam with the young, on finding a bird's nest, Deu 22:6 others, of killing, dressing, and eating a kid, while it sucks the milk of its mother, before it is eight days old, and so a law against luxury; but the Jews generally understand it of boiling, or eating the flesh of any creature and milk together (g): so the Targum of Onkelos paraphrases it,"ye shall not eat flesh with milk;''and the Targum of Jonathan is,"ye shall neither boil nor eat the flesh and the milk mixed together:''hence, according to the rules they give, the flesh of any beast, or of a fowl, is not to be set upon a table on which cheese is (being made of milk), lest they should be eaten together; nor may cheese be eaten after flesh until some considerable time, and then, if there is any flesh sticks between a man's teeth, he must remove it, and wash and cleanse his mouth; nor may cheese be eaten on a table cloth on which meat is, nor be cut with a knife that flesh is cut with (h): so careful are they of breaking this law, as they understand it: but the words are, doubtless, to be taken literally, of not boiling a kid in its mother's milk; and is thought by many to refer to some custom of this kind, either among the Israelites, which they had somewhere learnt, or among the idolatrous Heathens, and therefore cautioned against; Maimonides and Abarbinel both suppose it was an idolatrous rite, but are not able to produce an instance of it out of any writer of theirs or others: but Dr. Cudworth has produced a passage out of a Karaite author (i), who affirms,"it was a custom of the Heathens at the ingathering of their fruits to take a kid and seethe it in the milk of the dam, and then, in a magical way, go about and besprinkle all their trees, fields, gardens, and orchards, thinking by this means they should make them fructify, and bring forth fruit again more abundantly the next year:''and the Targum of Jonathan on Exo 34:26 seems to have respect to this, where, having paraphrased the words as here quoted above, adds,"lest I should destroy the fruit of your trees with the unripe grape, the shoots and leaves together:''and if this may be depended upon, the law comes in here very aptly, after the feast of ingathering, and the bringing in the first fruits of the land into the Lord's house.

Three times . . . keep a feast . . . in the year--This was the institution of the great religious festivals--"The feast of unleavened bread," or the passover--"the feast of harvest," or pentecost--"the feast of ingathering," or the feast of tabernacles, which was a memorial of the dwelling in booths in the wilderness, and which was observed in the seventh month (Exo 12:2). All the males were enjoined to repair to the tabernacle and afterwards the temple, and the women frequently went. The institution of this national custom was of the greatest importance in many ways: by keeping up a national sense of religion and a public uniformity in worship, by creating a bond of unity, and also by promoting internal commerce among the people. Though the absence of all the males at these three festivals left the country defenseless, a special promise was given of divine protection, and no incursion of enemies was ever permitted to happen on those occasions.
