Genesis 24:60

And they blessed Rebekah, and said unto her, thou art our sister, be thou the mother of thousands of millions, and let thy seed possess the gate of those which hate them. That the number of Rebekah's descendants might be a countless host and that all her progeny might always be victorious against all their enemies, that was the sincere and loving blessing which the relatives that dismissed her with a heavy heart laid upon her. The work of Eliezer in the suit of Rebekah having begun so auspiciously, God Himself having manifestly blessed the betrothal, it was best to hurry forward to the consummation of marriage, lest evil tongues sow discord.
