Genesis 24:3

Genesis 24:3. And I will make thee swear by the LORD, the God of heaven, And the God of the earth, that thou shalt not take a wife unto my son of the daughters of the Canaanites, among whom I dwell:

This holy man was careful of the purity of his family; he knew what an ill-effect a Canaanitish wife might have upon his son, and also upon his offspring. He was, therefore, particularly careful here. I would that all parents were the same.
