1 Kings 15:17

Baasha built Ramah That is, repaired and fortified it. It was a city in the tribe of Benjamin, which either belonged to the kingdom of Israel, or he had taken it from Judah. That he might not suffer any to go out, &c. That he might hinder all communication between his people and the people of Judah, and that his people might not go up to Jerusalem to worship. For this place lay in the confines of both kingdoms; and in such a strait, that a fortification being made there, none could pass to or fro without a license from Baasha.
