In the selfsame day was Abraham circumcised, and Ishmael
his
son.
] This is repeated, that it might be taken notice of that both
were circumcised according to the command of God, and on the very
day in which it was given. Jarchi observes, it was in the day,
and not in the night; which shows, says he, he was not afraid of
the Heathen, and of mockers; and that his enemies, and the men of
that generation, might not say, if we had seen him, we would not
have suffered him to be circumcised, and keep the commandment of
God: and some of the Jewish writers F5 fable, that he was
circumcised on the day afterwards appointed by Moses for the day
of atonement, and that in the place where he was circumcised the
altar was built; but all this is without any foundation. This
affair was transacted, according to Bishop Usher {f}, A. M. 2107,
and before Christ 1897.
