Genesis 24:7

The Lord God of heaven, which took me from my father's house and from the land of my kindred, and which spake unto me, and that sware unto me, saying, Unto thy seed will I give this land, he shall send His angel before thee, and thou shalt take a wife unto my son from thence. That was the argument of faith: Jehovah had brought Abraham into the land in which he was now sojourning as a stranger; Jehovah had, with a solemn oath, promised this land to his descendants; therefore Jehovah would crown the servant's venture in Abraham's name with success, through the guidance and protection of His angel.
