Verse 5
Gave him none inheritance - Both Abraham and Jacob had small parcels of land in Canaan; but they had them by purchase, not by God's gift; for, as Abraham was obliged to buy a burying-place in Canaan, Genesis 23:3-18, it is obvious he had no inheritance there.
And to his seed after him - See Gen 12:7 (note); Gen 13:15, and the notes there.
