Jeremiah 29:4-6

Thus saith Jehovah of hosts, the God of Israel, unto all the captivity, whom I have caused to be carried away captive from Jerusalem unto Babylon: Build ye houses, and dwell in them; and plant gardens, and eat the fruit of them. Take ye wives, and beget sons and daughters; and take wives for your sons, and give your daughters to husbands, that they may bear sons and daughters: and multiply ye there, and be not diminished.
