28 The prophet visited the king of Israel and said, “This is what the Lord has said: ‘Because the Syrians said, “The Lord is a god of the mountains and not a god of the valleys,” I will deliver this entire huge army into to your control. Then you will know that I am the Lord.’

Darby

28 And the man of God drew near, and spoke to the king of Israel and said, Thus saith Jehovah: Because the Syrians have said, Jehovah is a god of the mountains, but he is not a god of the valleys, I will give all this great multitude into thy hand, and ye shall know that I am Jehovah.

KJV

28 And there came a man of God, and spake unto the king of Israel, and said, Thus saith the LORD, Because the Syrians have said, The LORD [is] God of the hills, but he [is] not God of the valleys, therefore will I deliver all this great multitude into thine hand, and ye shall know that I [am] the LORD.
