'Forty two' in the Bible

When he turned around and looked at them, he cursed them in the name of the Lord. Then two female bears came out of the woods and tore to pieces forty-two of the boys.

Then Jehu said, “Take them alive.” So they took them alive and [later] slaughtered them at the well by the place of the sand heaps, forty-two men; he left none of them [alive].
