Kinaumagahan, maagang bumangon si Abraham at siniyahan ang kanyang asno. Isinama niya ang dalawa sa kanyang mga kabataang lingkod at si Isaac na kanyang anak. Nagsibak siya ng kahoy para sa handog na susunugin, at tumindig siya at pumunta sa lugar na sinabi sa kanya ng Diyos.
Mishneh Torah, Circumcision
Circumcisions are only performed during the daytime after sunrise, whether the operation takes place on the eighth day, the regular time, or subsequently, from the ninth day and further on, as it is said "on the eighth day" (Gen. 17:12) i.e. by day, and not at night. If the circumcision takes place after daybreak, it is correct. The whole of the day is proper for circumcision. Still it is a duty to perform it in the early part of the day, for the zealous fulfill their religious obligations at the earliest possible time.
