Genesis 49:22

“Joseph is a fruitful bough, etc.] Or as one, like the bough or branch of a tree laden with fruit, as he was with children; one of which he called Ephraim from his fruitfulness, and both his sons became numerous, and the heads of two tribes in Israel; and with other temporal fruits and blessings, as riches, honour, etc. and especially with the fruits of grace and righteousness: [even] a fruitful bough by a well; those are the most fruitful that are near a well or fountain of water, as such trees are which are planted by rivers of water, (see <190103>Psalm 1:3) this being repeated may have respect to the two boughs or branches of Joseph’s family, or the two fruitful and numerous tribes that…”

“JOSEPH-- (Gen 49:22-26) a fruitful bough, &c.--denotes the extraordinary increase of that tribe (compare Num 1:33-35; Jos 17:17; Deu 33:17). The patriarch describes him as attacked by envy, revenge, temptation, ingratitude; yet still, by the grace of God, he triumphed over all opposition, so that he became the sustainer of Israel; and then he proceeds to shower blessings of every kind upon the head of this favorite son. The history of the tribes of Ephraim and Manasseh shows how fully these blessings were realized.”

Deuteronomy 5:14; Psalms 60:9; Psalms 108:9; Isaiah 33:22; in five of which it clearly denotes ruler, or judge. The meaning “sceptre” is therefore doubtful. שׁילה shı̂ylôh, Shiloh, a softened form of שׁילון shı̂ylôn, a derivative of שׁל shol, the ultimate root of שׁלה shālâh, שׁלם shālam, and possibly שׁלט shālaṭ, and hence, denoting “the peacemaker, the prince of peace.” It…”

“49:22-26 This oracle treats Joseph more expansively than any of the others, for here the main blessing lay (see 1 Chr 5:1-2). Jacob lavished promises of victory and prosperity on Joseph’s two tribes. Ephraimites recorded as victorious in battle include Joshua (Josh 6, 8, 10, 12) and Deborah (Judg 4). Victorious descendants of Manasseh include Gideon (Judg 6–8) and Jephthah (Judg 11:1–12:7).”
