Reuben, as the first-born by nature, has the first place in the benedictory address. My might. In times and places in which a man's right depends on his might, a large family of sons is the source of strength and safety. "The excellency of dignity, and the excellency of power" - the rank and authority which belong to the first-born. "Boiling over as water." That which boils over perishes at the same time that it is pernicious. This is here transferred in a figure to the passionate nature of Reuben. "Thou shalt not excel." There is here an allusion to the excellency of dignity and power. By the boiling over of his unhallowed passions Reuben lost all the excellence that primogeniture confers. By the dispensation of Providence the double portion went to Joseph, the first-born of Rachel; the chieftainship to Judah; and the priesthood to Levi. The cause of this forfeiture is then assigned. In the last sentence the patriarch in a spirit of indignant sorrow passes from the direct address to the indirect narrative. "To my couch he went up." The doom here pronounced upon Reuben is still a blessing, as he is not excluded from a tribe's share in the promised land. But, as in the case of the others, this blessing is abated and modified by his past conduct. His tribe has its seat on the east of the Jordan, and never comes to any eminence in the commonwealth of Israel.

Reuben as the first-born had a right to a double portion of all that the father had; see Deuteronomy 21:17

The eminence or dignity mentioned here may refer to the priesthood; the power, to the regal government or kingdom - In this sense it has been understood by all the ancient Targumists. The Targum of Onkelos paraphrases it thus: "Thou shouldst have received three portions, the birthright, the priesthood, and the kingdom:" and to this the Targums of Jonathan ben Uzziel and Jerusalem add: "But because thou hast sinned, the birthright is given to Joseph, the kingdom to Judah, and the priesthood to Levi." That the birthright was given to the sons of Joseph we have the fullest proof from 1 Chronicles 5:1.

Reuben, thou art my firstborn,.... Jacob addressed himself to Reuben first, in the presence of his brethren, owned him as his firstborn, as he was, Genesis 29:31 did not cashier him from his family, nor disinherit him, though he had greatly disobliged him, for which the birthright, and the privileges of it, were taken from him, 1 Chronicles 5:1.

my might, and the beginning of my strength; begotten by him when in his full strength (z), as well as the first of his family, in which his strength and glory lay; so the Septuagint, "the beginning of my children"; and because he was so, of right the double portion belonged to him, had he not forfeited it, Deuteronomy 21:17. Some versions render the words, "the beginning of my grief", or "sorrow" (a), the word "Oni" sometimes so signifying, as Rachel called her youngest son "Benoni", the son of my sorrow; but this is not true of Reuben, he was not the beginning of Jacob's sorrow, for the ravishing of Dinah, and the slaughter and spoil of the Shechemites, by his sons, which gave him great sorrow and grief, were before the affair of Reuben's lying with Bilhah:

the excellency of dignity, and the excellency of power; that is, to him of right belonged excellent dignity, power, and authority in the family, a preeminence over his brethren, a double portion of goods, succession in government, and, as is commonly understood, the exercise of the priesthood; and so the Targums interpret it, that he should, had he not sinned, took three parts or portions above his brethren, the birthright, priesthood, and kingdom. Jacob observes this to him, that he might know what he had lost by sinning, and from what excellency and dignity, grandeur and power, he was fallen.

Reuben, my first-born thou, my might and first-fruit of my strength; pre-eminence in dignity and pre-eminence in power. - As the first-born, the first sprout of the full virile power of Jacob, Reuben, according to natural right, was entitled to the first rank among his brethren, the leadership of the tribes, and a double share of the inheritance (Genesis 27:29; Deuteronomy 21:17). (שׂאת: elevation, the dignity of the chieftainship; עז, the earlier mode of pronouncing עז, the authority of the first-born.) But Reuben had forfeited this prerogative. "Effervescence like water - thou shalt have no preference; for thou didst ascend thy father's marriage-bed: then hast thou desecrated; my couch has he ascended." פּחז: lit., the boiling over of water, figuratively, the excitement of lust; hence the verb is used in Judges 9:4; Zephaniah 3:4, for frivolity and insolent pride. With this predicate Jacob describes the moral character of Reuben; and the noun is stronger than the verb פחזת of the Samaritan, and אתרעת or ארתעת efferbuisti, aestuasti of the Sam. Vers., ἐξύβρισας of the lxx, and ὑπερζέσας of Symm. תּותר is to be explained by יתר: have no pre-eminence. His crime was, lying with Bilhah, his father's concubine (Genesis 35:22). חלּלתּ is used absolutely: desecrated hast thou, sc., what should have been sacred to thee (cf. Leviticus 18:8). From this wickedness the injured father turns away with indignation, and passes to the third person as he repeats the words, "my couch he has ascended." By the withdrawal of the rank belonging to the first-born, Reuben lost the leadership in Israel; so that his tribe attained to no position of influence in the nation (compare the blessing of Moses in Deuteronomy 33:6). The leadership was transferred to Judah, the double portion to Joseph (1 Chronicles 5:1-2), by which, so far as the inheritance was concerned, the first-born of the beloved Rachel took the place of the first-born of the slighted Leah; not, however, according to the subjective will of the father, which is condemned in Deuteronomy 21:15., but according to the leading of God, by which Joseph had been raised above his brethren, but without the chieftainship being accorded to him.

Reuben, thou art my firstborn, my {b} might, and the beginning of my strength, {c} the excellency of dignity, and the excellency of power:

(b) Begotten in my youth.

(c) If you have not left your birthright by your offence.

49:3 Reuben thou art my first - born - Jacob here puts upon him the ornaments of the birth - right, that he and all his brethren might see what he had forfeited and in that might see the evil of his sin. As the first - born he was his father's joy, being the beginning of his strength. To him belonged the excellency of dignity above his brethren, and some power over them.

Ge 49:3, 4. Reuben forfeited by his crime the rights and honors of primogeniture. His posterity never made any figure; no judge, prophet, nor ruler, sprang from this tribe.

49:3-7 Reuben was the first-born; but by gross sin, he forfeited the birthright. The character of Reuben is, that he was unstable as water. Men do not thrive, because they do not fix. Reuben's sin left a lasting infamy upon his family. Let us never do evil, then we need not fear being told of it. Simeon and Levi were passionate and revengeful. The murder of the Shechemites is a proof of this. Jacob protested against that barbarous act. Our soul is our honour; by its powers we are distinguished from, and raised above, the beasts that perish. We ought, from our hearts, to abhor all bloody and mischievous men. Cursed be their anger. Jacob does not curse their persons, but their lusts. I will divide them. The sentence as it respects Levi was turned into a blessing. This tribe performed an acceptable service in their zeal against the worshippers of the golden calf, Ex 32. Being set apart to God as priests, they were in that character scattered through the nation of Israel.
