'Childless' in the Bible

"Teacher," they said, "Moses enjoined, 'If a man die childless, his brother shall marry his widow, and raise up a family for him.'

Now we had among us seven brothers. The eldest of them married, but died childless, leaving his wife to his brother.

The second also [died childless], and the third, down to the seventh.

And so did the rest of the seven, all dying childless. Finally the woman also died.

“Teacher, Moses wrote for us that if a man’s brother has a wife, and dies childless, his brother should take the wife and produce offspring for his brother.

Now there were seven brothers. The first one married and died childless.

And the second took her to wife, and he died childless.

He didn’t give him an inheritance in it, not even a foot of ground, but He promised to give it to him as a possession, and to his descendants after him, even though he was childless.

For it is written, "Rejoice, you childless woman, who cannot give birth to any children! Break into song and shout, you who feel no pains of childbirth! For the children of the deserted woman are more numerous than the children of the woman who has a husband."
