'Taunt' in the Bible

"This is what Hezekiah says: "Today is a day of trouble, rebuke, and blasphemy, because children are about to be born, but there is no strength to bring them to birth. Perhaps the LORD your God will take note of everything that Rab-shakeh has said, whom his master the king of Assyria sent to taunt the living God, and then he will rebuke the words that the LORD your God has heard. Therefore offer a prayer for the survivors who remain.'"
