'Fruit of the Womb' in the Bible

And Jacob's anger was kindled against Rachel: and he said, Am I in God's stead, who hath withheld from thee the fruit of the womb?

'And Jehovah hath made thee abundant in good, in the fruit of the womb, and in the fruit of thy cattle, and in the fruit of thy ground, on the ground which Jehovah hath sworn to thy fathers to give to thee.

Lo, children are an heritage of the LORD: and the fruit of the womb is his reward.

Their bows also shall dash the young men to pieces; and they shall have no pity on the fruit of the womb; their eye shall not spare children.
