'There's' in the Bible

After this, Elijah told Ahab, "Get up and have something to eat and drink, because there's the sound of a coming rainstorm."

But Elijah told him to go back seven times. On the seventh look, he said, "Look! There's a cloud, a small one, about the size of a man's hand. It's coming up out of the sea!" "Get up and find Ahab!" Elijah said. "Tell him, "Mount your chariot and ride down the mountain so the storm doesn't stop you.'"
