Gilead is mine, and Manasseh is mine; Ephraim also is the strength of mine head; Judah is my lawgiver; Gilead is mine - This country was also beyond Jordan, and Manasseh and Ephraim are put for the tribes that formed the kingdom of Israel. All these, after the return from the captivity, formed but one people, the Jews and Israelites being united.
The strength of mine head - It shall be the principal support of the new-found kingdom, when all distinctions shall be buried.
Judah is my lawgiver - This tribe was chief of all those who returned from the captivity; and Zerubbabel, who was their leader, was chief of that tribe, and of the family of David. As this part of the Psalm appears to relate to the return of the captives from Babylon, and their repossession of their own land, the psalmist may refer, not only to the promises of their restoration, but also to the principal person under whose superintendence they returned.
