From which town came the prophet Jonah, who foretold King Jeroboam's restoring of Israel's borders?

Answer: Gath-hepher

Jeroboam son of Jehoash restored Israel's border, as the LORD had said through Jonah son of Amittai, the prophet from Gath-hepher.

“This Jeroboam restored the boundary of Israel from Lebo-hamath to the Sea of the Arabah, according to the word that the LORD, the God of Israel, had spoken through His servant Jonah son of Amittai, the prophet from Gath-hepher.”— 2 Kings 14:25 (BSB)
