Jeremiah 29:5-6, 28

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; that ye may be increased there, and not diminished.

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.
