God had commanded him.
] ( Genesis 17:12 ) , and was the first that we read of that was circumcised on that day, according to the divine precept, which Abraham strictly observed; for though this was the son of the promise, and of his old age, for whom he had the most affectionate regard, yet he administered this bloody ordinance on him; nor did he defer it beyond the time, and was himself the operator, as it seems; all which shows his strict regard, and ready and cheerful obedience to the command of God.
