Genesis 48:4

“May God Almighty bless you and make you fruitful and multiply you, that you may become an assembly of peoples.

God also said to him, “I am God Almighty; Be fruitful and multiply; A nation and an assembly of nations shall come from you, And kings shall come forth from your loins.

But the sons of Israel were fruitful and increased and multiplied and became exceedingly mighty, so that the land was filled with them.

‘So I will turn toward you and make you fruitful and multiply you, and I will confirm My covenant with you.

Behold, children are an inheritance of Yahweh, The fruit of the womb is a reward.
