Here is, I. The blessing of Reuben. Though Reuben had lost the honour of his birthright, yet Moses begins with him; for we should not insult over those that are disgraced, nor desire to perpetuate marks of infamy upon any, though ever so justly fastened at first, Deu 33:6. Moses desires and foretels, 1. The preserving of this tribe. Though a frontier tribe on the other side Jordan, yet, "Let it live, and not be either ruined by its neighbours or lost among them." And perhaps he refers to those chosen men of that tribe who, having had their lot assigned them already, left their families in it, and were now ready to go over armed before their brethren, Num 32:27. "Let them be protected in this noble expedition, and have their heads covered in the day of battle." 2. Let it be a numerous tribe; though their other honours be lost, so that they shall not excel, yet let them multiply." Let Reuben live and not die, though his men be few; so bishop Patrick, thinks it may be rendered. "Though he must not expect to flourish (Gen 49:4), yet let him not perish." All the Chaldee paraphrasts refer this to the other world: Let Reuben live in life eternal, and not die the second death, so Onkelos. Let Reuben live in this world, and not die that death which the wicked die in the world to come, so Jonathan and the Jerusalem Targum.

II.The blessing of Judah, which is put before Levi because our Loud sprang out of Judah, and (as Dr. Lightfoot says) because of the dignity of the kingdom above the priesthood. The blessing (Deu 33:7) may refer either, 1. To the whole tribe in general. Moses prays for, and prophesies, the great prosperity of that tribe., That God would hear his prayers (see an instance, Ch2 13:14, Ch2 13:15), settle him in his lot, prosper him in all his affairs, and give him victory over his enemies. It is taken for granted that the tribe of Judah would be both a praying tribe and an active tribe. "Lord," says Moses, "hear his prayers, and give success to all his undertakings: let his hands be sufficient for him both in husbandry and in war." The voice of prayer should always be attended with the hand of endeavour, and then we may expect prosperity. Or, 2. It may refer in particular to David, as a type of Christ, that God would hear his prayers, Psa 20:1 (and Christ was heard always, Joh 11:42), that he would give him victory over his enemies, and success in his great undertakings. See Psa 89:20 etc. And that prayer that God would bring him to his people seems to refer to Jacob's prophecy concerning Shiloh, That to him should the gathering of the people be, Gen 49:10. The tribe of Simeon is omitted in the blessing, because Jacob had left it under a brand, and it had never done any thing, as Levi had done, to retrieve its honour. It was lessened in the wilderness more than any other of the tribes; and Zimri, who was so notoriously guilty in the matter of Peor but the other day, was of that tribe. Or, because the lot of Simeon was an appendage to that of Judah, that tribe is included in the blessing of Judah. Some copies of the Septuagint join Simeon with Reuben: Let Reuben live and not die; and let Simeon be many in number.

And of Levi he said,.... That is, Moses said of the tribe of Levi, as both the Targums of Jonathan and Jerusalem:

let thy Thummim and thy Urim be with thy Holy One; with Aaron, as the same Targums interpret it, who was of the tribe of Levi, and was a holy good man, a saint of the Lord, as he is called, Psa 106:16; of the Urim and Thummim, which were with him and with every high priest; see Gill on Exo 28:30; and though they were not in use under the second temple, yet had their fulfilment in Christ the antitype of Aaron, who may be chiefly here intended; who is after called the Lord's Holy One, as he is, both as God and man, holy in both his natures, divine and human, and in his life and actions; and with him are the true Urim and Thummim, lights and perfections, the light of nature, grace and glory, and all perfections, both divine and human; See Gill on Exo 28:30 (i):

whom thou didst prove at Massah, and with whom thou didst strive at the waters of Meribah; which, as it may respect Aaron, may be understood either of the Lord's proving him and contending with him, by suffering the children of Israel to murmur against him and Moses, at the said places; when, according to the three Targums, he stood in the temptation, and was perfect and found faithful; or of Levi, who, with the rest of the tribes, tried him, and strove with him at the same places; though Jarchi says they did not murmur with the rest that murmured: as it may refer to Christ the antitype of Levi, the sense is, that the Urim and Thummim should be with the Holy One, the Messiah, whom thou, O Levi, with the rest of the tribes, tempted and strove with at the places mentioned; for it is expressly said, they tempted the Lord, Exo 17:7; and which is interpreted of Christ, Co1 10:9.

(i) See a Sermon of mine on this text, called "Levi's Urim and Thummim Found with Christ".

this is the blessing of Judah--Its general purport points to the great power and independence of Judah, as well as its taking the lead in all military expeditions.
