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.

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.
