Mwanzo 17:23

Siku ile ile, Abrahamu akamchukua Ishmaeli mwanawe na wote waliozaliwa nyumbani mwake pamoja na walionunuliwa kwa fedha zake, kila mwanaume wa nyumbani mwake, akawatahiri, kama Mungu alivyomwagiza.

¶ And Abraham took Ishmael his son, and all that were born in his house, and all that were bought with his money, every male among the men of Abraham’s house; and circumcised the flesh of their foreskin in the selfsame day, as God had said unto him.
