Joshua 10:29,30

‘ And Joshua passed from Makkedah, and all Israel with him, to Libnah, and fought against Libnah. And YHWH delivered it also, and its king, into the hand of Israel. And he smote it with the edge of the sword, and all the souls who were in it. He left none remaining in it. And he did to its king as he had done to the king of Jericho.'

Libnah is another town whose site is unidentified. None of the suggestions made are really satisfactory. It was another of a series of towns in the Shephelah (lowlands). The city was captured, and its king and all its people put to the edge of the sword in the process, its king then being hung up until the evening after which he was buried, as had happened to the king of Jericho. Its cattle and spoils would be prizes to Israel. But as the reputation of Israel grew so would the number of people who would make their escape before they arrived.
