Sirach 16:

Desire not a multitude of unprofitable children, neither delight in ungodly sons.

Trust not thou in their life, neither respect their multitude: for one that is just is better than a thousand; and better it is to die without children, than to have them that are ungodly.

For by one that hath understanding shall the city be replenished: but the kindred of the wicked shall speedily become desolate.
