'Dwindle' in the Bible

Marry and have sons and daughters. Find wives for your sons and allow your daughters get married so that they too can have sons and daughters. Grow in number; do not dwindle away.

Out of those places you will hear songs of thanksgiving and the sounds of laughter and merriment. I will increase their number and they will not dwindle away. I will bring them honor and they will no longer be despised.
