Acts 7:1-8

And the high priest said, Are these things so? And he said, Brethren and fathers, hearken: The God of glory appeared unto our father Abraham, when he was in Mesopotamia, before he dwelt in Haran, and said unto him, Get thee out of thy land, and from thy kindred, and come into the land which I shall show thee. Then came he out of the land of the Chaldæans, and dwelt in Haran: and from thence, when his father was dead, God removed him into this land, wherein ye now dwell: and he gave him none inheritance in it, no, not so much as to set his foot on: and he promised that he would give it to him in possession, and to his seed after him, when as yet he had no child. And God spake on this wise, that his seed should sojourn in a strange land, and that they should bring them into bondage, and treat them ill, four hundred years. And the nation to which they shall be in bondage will I judge, said God: and after that shall they come forth, and serve me in this place. And he gave him the covenant of circumcision: and so Abraham begat Isaac, and circumcised him the eighth day; and Isaac begat Jacob, and Jacob the twelve patriarchs.
