[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 ( Psalms 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 ( Psalms 135:11 Psalms 135:12 ) . And thus the heavenly glory, of which Canaan was a type, is an inheritance owing to the mercy of our Lord Jesus Christ, ( Jude 1:21 ) .
