'Childless' in the Bible

He had two wives, the first named Hannah and the second Peninnah. Peninnah had children, but Hannah was childless.

Hannah’s rival provoked her bitterly, to irritate and embarrass her, because the Lord had left her childless.

And Samuel said, As thy sword hath made women childless, so shall thy mother be childless among women. And Samuel hewed Agag in pieces before the LORD in Gilgal.
