Here is, I. Care taken for the due administration of justice among them, that controversies might be determined, matters in variance adjusted, the injured redressed, and the injurious punished. While they were encamped in the wilderness, they had judges and officers according to their numbers, rulers of thousands and hundreds, Exo 18:25. When they came to Canaan, they must have them according to their towns and cities, in all their gates; for the courts of judgment sat in the gates. Now, 1. Here is a commission given to these inferior magistrates: "Judges to try and pass sentence, and officers to execute their sentences, shalt thou make thee." However the persons were pitched upon, whether by the nomination of their sovereign or by the election of the people, the power were ordained of God, Rom 13:1. And it was a great mercy to the people thus to have justice brought to their doors, that it might be more expeditious and less expensive, a blessing which we of this nation ought to be very thankful for. Pursuant to this law, besides the great sanhedrim that sat at the sanctuary, consisting of seventy elders and a president, there was in the larger cities, such as had in them above 120 families, a court of twenty-three judges, in the smaller cities a court of three judges. See this law revived by Jehoshaphat, Ch2 19:5, Ch2 19:8. 2. Here is a command given to these magistrates to do justice in the execution of the trust reposed in them. Better not judge at all than not judge with just judgment, according to the direction of the law and the evidence of the fact. (1.) The judges are here cautioned not to do wrong to any (Deu 16:19), nor to take any gifts, which would tempt them to do wrong. This law had been given before, Exo 23:8. (2.) They are charged to do justice to all: "That which is altogether just shalt thou follow, Deu 16:20. Adhere to the principles of justice, act by the rules of justice, countenance the demands of justice, imitate the patterns of justice, and pursue with resolution that which appears to be just. Justice, justice, shalt thou follow." This is that which the magistrate is to have in his eye, on this he must be intent, and to this all personal regards must be sacrificed, to do right to all and wrong to none.

II.Care taken for the preventing of all conformity to the idolatrous customs of the heathen, Deu 16:21, Deu 16:22. They must not only not join with the idolaters in their worships, not visit their groves, nor bow before the images which they had set up, but, 1. They must not plant a grove, nor so much as a tree, near God's altar lest they should make it look like the altars of the false gods. They made groves the places of their worship either to make it secret (but that which is true and good desires the light rather), or to make it solemn, but the worship of the true God has enough in itself to make it so and needs not the advantage of such a circumstance. 2. They must not set up any image, statue, or pillar, to the honour of God, for it is a thing which the Lord hates; nothing belies or reproaches him more, or tends more to corrupt and debauch the minds of men, than representing and worshipping by an image that God who is an infinite and eternal Spirit.

Thou shall not plant thee a grove of any trees,.... Of any sort of trees, as oaks or any other; not but that it was lawful to plant trees and groves of them, but not for a religious or idolatrous use: particularly

near unto the altar of the Lord thy God, which thou shalt make thee; as the Heathens did near their altars, lest it should be thought to be done for a like superstitious and idolatrous use; which evil the Jews sometimes fell into in the times of wicked reigns, and which their good and pious kings removed and destroyed; see Kg2 18:4 and Hecataeus (b), an Heathen historian, relates of the city of Jerusalem, that there were there no image, nor plantation, nor grove, nor any such thing.

(b) Apud Euseb. Praepar. Evangel. l. 9. c. 4. p. 408.

Judges and officers shalt thou make--These last meant heralds or bailiffs, employed in executing the sentence of their superiors.

in all thy gates--The gate was the place of public resort among the Israelites and other Eastern people, where business was transacted and causes decided. The Ottoman Porte derived its name from the administration of justice at its gates.
