'Child' in the Bible

So Boaz took Ruth and she became his wife; and he went in to her, and the Lord made her with child and she gave birth to a son.

And Naomi took the child, and laid it in her bosom, and became nurse unto it.

So her women neighbors gave the child a nickname, which is "Naomi has a son!" They named him Obed. He became the father of Jesse, who was the father of David.
