Adam Clarke's Bible Commentary Verse 3. That thou mayest be a multitude of people] µym[ lhql likhal ammim. There is something very remarkable in the original words: they signify literally for an assembly, congregation, or church of peoples; referring no doubt to the Jewish Church in the wilderness, but more particularly to the Christian Church, composed of every kindred, and nation, and people, and tongue. This is one essential part of the blessing of Abraham. See Genesis xxviii. 4.
Matthew Henry Commentary
Verses 1-5 - Jacob had blessings promised both as to this world and that which is to come; yet goes out to a hard service. This corrected him for the frau on his father. The blessing shall be conferred on him, yet he shal smart for the indirect course taken to obtain it. Jacob is dismissed by his father with a solemn charge. He must not take a wife of the daughters of Canaan: those who profess religion, should not marry with those that care not for religion. Also with a solemn blessing. Isaa had before blessed him unwittingly; now he does it designedly. Thi blessing is more full than the former; it is a gospel blessing. Thi promise looks as high as heaven, of which Canaan was a type. That wa the better country which Jacob and the other patriarchs had in view.
