Abraham asked his servant to arrange a marriage for his son, Isaac:
And Abraham said to his servant, the oldest of his house, who had charge of all that he had, "Put your hand under my thigh, and I will make you swear by the LORD, the God of heaven and of the earth, that you will not take a wife for my son from the daughters of the Canaanites, among whom I dwell, but will go to my country and to my kindred, and take a wife for my son Isaac." Genesis 24:2-4
However, that servant did pray to Yahweh, asking Him to show him which woman He had appointed for Isaac.
