Even an heritage unto Israel his servant,.... The land of those that served idols, the Lord took and gave to Israel for an inheritance, who served him, the true God. Thus the Lord rewards his servants in a way of grace and mercy, though not as of debt; for it follows,
for his mercy endureth for ever; Aben Ezra and Kimchi make the mercy to lie in this peculiarly, that the lands of these kings were not in the covenant with Abraham; only the seven nations or kingdoms of Canaan, which are not here mentioned, as in Psalm 135:11; but the Amorites were given in the covenant, Genesis 15:21; and the one as the other were given as an inheritance to Israel, and equally owing to the mercy of God; see Psalm 135:11. And thus the heavenly glory, of which Canaan was a type, is an inheritance owing to the mercy of our Lord Jesus Christ, Jde 1:21.

Israel - He speaks of all that people as of one man, because they were united together in one body in the worship of God.
