Jeremiah 29:4, 6-7, 10-11, 28

Thus saith the LORD of hosts, the God of Israel, unto all that are carried away captives, whom I have caused to be carried away from Jerusalem unto Babylon

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; that ye may be increased there, and not diminished. And seek the peace of the city whither I have caused you to be carried away captives, and pray unto the LORD for it: for in the peace thereof shall ye have peace.

For thus saith the LORD, That after seventy years be accomplished at Babylon I will visit you, and perform my good word toward you, in causing you to return to this place. For I know the thoughts that I think toward you, saith the LORD, thoughts of peace, and not of evil, to give you an expected end.

For therefore he sent unto us in Babylon, saying, This captivity is long: build ye houses, and dwell in them; and plant gardens, and eat the fruit of them.
