So God created man in his own image, in the image of God he created him; male and female he created them.
God blessed them and said to them, "Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish of the sea and the birds of the air and over every living creature that moves on the ground."
Genesis Chapter 1: Verses 27 - 28
Then Judah said to Onan, "Lie with your brother's wife and fulfill your duty to her as a brother-in-law to produce offspring for your brother."
But Onan knew that the offspring would not be his; so whenever he lay with his brother's wife, he spilled his semen on the ground to keep from producing offspring for his brother.
What he did was wicked in the LORD's sight; so he put him to death also.
Genesis Chapter 38: Verses 8 - 10
Sons are a heritage from the LORD, children a reward from him.
Like arrows in the hands of a warrior are sons born in one's youth.
Blessed is the man whose quiver is full of them. They will not be put to shame when they contend with their enemies in the gate.
Psalms Chapter 127: Verses 3 - 5
This is what the LORD Almighty, the God of Israel, says to all those I carried into exile from Jerusalem to Babylon:
"Build houses and settle down; plant gardens and eat what they produce.
Marry and have sons and daughters; find wives for your sons and give your daughters in marriage, so that they too may have sons and daughters. Increase in number there; do not decrease.
Jeremiah Chapter 29: Verses 4 - 6
