Abraham
In the Book of Genesis, Abraham leaves his home in Mesopotamia for Canaan because the Almighty told him to go there and become the ancestor of a great nation. At the time, his name was Abram but then the Almighty told him to circumcise himself and all his sons and that “the uncircumcised male who dwells among you, his soul shall be cut off, for he has rejected my covenant” and after his circumcision Abram changed his name to Abraham.
