There is a Biblical phrase "The fruit of Thy womb, Jesus addressed to the Blessed Virgin.

The Hail Mary: Hail Mary, full of grace; the Lord is with thee. Blessed art thou among women, and blessed is the fruit of thy womb, Jesus.

In the bible itself the phrase "fruit of the womb" appears repeatedly, the earliest being Genesis 30:2: 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?

However, the phrase apparently never appears -- King James Version -- as "fruit of thy womb, Jesus", even in those cases where it is referring to Jesus.
