'Valleys' in the Bible

Then Ahab said to Obadiah, “Go through the land to all the springs of water and to all the valleys; perhaps we will find grass and keep the horses and mules alive, and not have to kill some of the cattle.”

Then a man of God came near and spoke to the king of Israel and said, “Thus says the Lord, ‘Because the Arameans have said, “The Lord is a god of the mountains, but He is not a god of the valleys,” therefore I will give all this great multitude into your hand, and you shall know that I am the Lord.’”
