'Child' in the Bible

Therefore the Lord himself will give you a sign. Look! the virgin [is] with child and she is about to give birth [to] a son, and she shall call his name 'God with us.'

For a child has been born for us; a son has been given to us. And the dominion will be on his shoulder, and his name is called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace.

Can a woman forget her suckling, [refrain] from having compassion on the child of her womb? Indeed, these may forget, but I, I will not forget you!
