Gilead is mine, and Manasseh is mine; Ephraim also is the strength of mine head; Judah is my lawgiver;
Gilead is mine, and Manasseh is mine. The very language of Jacob is referred to in Genesis 48:5, "Ephraim and Manasseh ... are mine, as Reuben and Simeon they shall be mine." Gilead and Manasseh are connected with Succoth, as comprising all the region east of Jordon.
Ephraim also is the strength of mine head - i:e., is the fortress which protects my head, the most vital part (Psalms 27:1; Psalms 68:21). Ephraim and Judah were the chief tribes of the nation west of Jordan. Ephriam was eminent for its power and riches (Genesis 48:19; Deuteronomy 33:17).
Judah is my lawgiver - as being Israel's ruling tribe. The reference is to Genesis 49:10, "The sceptre shall not depart from, Judah, nor a lawgiver from between his feet."
