3. We shall have the profit of it: I will feed thee with the heritage of Jacob thy father, that is, with all the blessings of the covenant and all the precious products of Canaan (which was a type of heaven), for these were the heritage of Jacob. Observe, The heritage of believers is what they shall not only be portioned with hereafter, but fed with now, fed with the hopes of it, and not flattered, fed with the earnests and foretastes of it; and those that are so fed have reason to say that they are well fed. In order that we may depend upon it, it is added, "The mouth of the Lord has spoken it; you may take God's word for it, for he cannot lie nor deceive; what his mouth has spoken his hand will give, his hand will do, and not one iota or tittle of his good promise shall fall to the ground." Blessed, therefore, thrice blessed, is he that doeth this, and lays hold on it, that keeps the sabbath from polluting it.
