'Womb' in the Bible

'Before I form thee in the belly, I have known thee; and before thou comest forth from the womb I have separated thee, a prophet to nations I have made thee.'

Because he hath not put me to death from the womb, And my mother is to me -- my grave, And her womb a pregnancy age-during.

Why is this? from the womb I have come out, To see labour and sorrow, Yea, consumed in shame are my days!
