17:23-27 Abraham and all his family were circumcised; so receiving the token of the covenant, and distinguishing themselves from other families that had no part nor lot in the matter. It was an implicit obedience; he did as God said unto him, and did not ask why or wherefore. He did it because God bade him. It was a speedy obedience; in the self-same day. Sincere obedience makes no delay. Not only the doctrines of revelation, but the seals of God's covenant, remind us that we are guilty, polluted sinners. They show us our need of the blood of atonement; they point to the promised Saviour, and teach us to exercise faith in him. They show us that without regeneration, and sanctification by his Spirit, and the mortification of our corrupt and carnal inclinations, we cannot be in covenant with God. But let us remember that the true circumcision is that of the heart, by the Spirit, Ro 2:28,29. Both under the old and new dispensation, many have had the outward profession, and the outward seal, who were never sealed by the Holy Spirit of promise.In the self-same day. - In this passage we have the prompt and punctual fulfillment of the command concerning circumcision detailed with all the minuteness due to its importance. Ishmael was thirteen years of age when he was circumcised. Josephus relates that the Arabs accordingly delay circumcision until the thirteenth year (Ant. I. 12. 2).

2. השׂתחיה vayı̂śtachû "bow," or bend the body in token of respect to God or man. The attitude varies from a slight inclination of the body to entire prostration with the forehead touching the ground.

6. סאה se'ah a "seah," about an English peck, the third part of an ephah. The ephah contained ten omers. The omer held about five pints.

This chapter describes Abraham's fellowship with God. On the gracious assurance of the Redeemer and Vindicator, "Fear not, I am thy shield and thy exceeding great reward," he ceased to fear, and believed. On the solemn announcement of the Conqueror of evil and the Quickener of the dead, "I am God Almighty; walk before me and be perfect," he began anew to walk with God in holiness and truth. The next step is, that God enters into communion with him as a man with his friend Isaiah 41:8; John 14:23. Hitherto he has appeared to him as God offering grace and inclining the will to receive it. Now, as God who has bestowed grace, he appears to him who has accepted it and is admitted into a covenant of peace. He visits him for the twofold purpose of drawing out and completing the faith of Sarah, and of communing with Abraham concerning the destruction of Sodom.

19, 20. The blessings of the covenant are reserved for Isaac, but common blessings were abundantly promised to Ishmael; and though the visible Church did not descend from his family, yet personally he might, and it is to be hoped did, enjoy its benefits. Circumcised the flesh of their foreskin; partly by his own hand, and partly by the help of others, whom he by Divine instinct called to and directed in that work;

in the self-same day, in which God appeared to him and gave the command. So he made haste and delayed not to execute God’s command. And his servants also yielded a ready and cheerful obedience to this severe and painful precept, being moved thereunto by Abraham’s example and sovereign authority, by God’s powerful presence some way or other manifested to them, and by the prospect and hope of God’s blessing to accompany and follow his own ordinance.

And Abraham took Ishmael his son,.... To circumcise him; he took his son first, to set an example to his servants, and that they might the more readily comply when they saw that Abraham's son, and at that time his only son, was circumcised before their eyes:

and all that were born in his house; which were three hundred and eighteen when he rescued Lot from the kings, Genesis 14:14; and perhaps they might be now increased:

and all that were bought with his money; how many those were, it is not easy to say, no doubt they were many:

every male among the men of Abraham's house; whether children or servants, and those little or grown up:

and circumcised the flesh of their foreskin, in the selfsame day, as God had said unto him; he performed this operation in the manner God directed him, the same day he spoke to him of it; he was not disobedient, nor dilatory to obey the command of God, but at once complied with it, not consulting flesh and blood, not regarding the pain he and his should endure, or the shame or danger they should be exposed unto through the Heathens about them; but trusting in God, and committing himself to him, and having his fear before his eyes, he hesitated not, but cheerfully did the will of God. In doing this work he might have some assistance: it is highly probable he began it himself, and circumcised several; and having taught some of his servants how to perform it according to the divine prescription, they might assist him in going through with it.

And Abraham took Ishmael his son, and all that were born in his house, and all that were bought with his money, every male among the men of Abraham's house; and {h} circumcised the flesh of their foreskin in the selfsame day, as God had said unto him.

(h) They were well taught if they obeyed and were circumcised without resistance. This teaches that masters in their houses ought to be as preachers to their families, that from the highest to the lowest they may obey the will of God.
