For I know him, that he will command his children and his household after him, and they shall keep the way of the LORD, to do justice and judgment; that the LORD may bring upon Abraham that which he hath spoken of him.
For I know him, that he will command. Kennicott renders it, 'I know him, that, he constantly commands;' Genenius, "I have chosen him, that he may command' (taking the verb 'know' in the sense in which it is used in Amos 3:2, as = regarded, loved).
Keep the way of the Lord, to do justice and judgment - i:e. to be sincerely pious toward God, and upright in all their social intercourse and transactions with the world. All the dependents and servants of Abraham's household being introduced into the privileges, were taught also the duties, of God's people; and if the simple genuine piety of the oldest servant be taken as a sample of the rest in that large establishment, we may perceive what a mighty moral influence must have been diffused by this family, which was destined to be the preserving salt of the earth-the little leaven that was to leaven the universal mass of corrupt humanity.
That the Lord may bring upon Abraham that which he hath spoken of him. His habitual attention to, and faithful performance of, these duties, was a compliance with the conditions on which the divine promises had been made to him.
