Genesis 17:11-13

Contemporary English Version

^10-11 (A) As the sign that you are keeping this promise, you must circumcise every man and boy in your family. ^12-13 From now on, your family must circumcise every baby boy when he is eight days old. You must even circumcise any man or boy you have as a slave, both those born in your homes and those you buy from foreigners. This will be a sign that my promise to you will last forever.
