Then Avraham took his son Yishmael, and all those born in his house… and he circumcised the flesh of their foreskins on that very day…
Classic midrash (same-day circumcision of the household)
English: On that very day — by day and not by night, so that neither enemies nor angels could say: had it been night he would not have done it. He acted at once on the day of the command.
