Isaiah 37:5

3 to tell him, “This is what Hezekiah says: Today is a day of distress, rebuke, and disgrace; for children have come to the point of birth, but there is no strength to deliver them.

4 Perhaps the LORD your God will hear the words of the Rabshakeh, whom his master the king of Assyria has sent to defy the living God, and He will rebuke him for the words that the LORD your God has heard. Therefore lift up a prayer for the remnant that still survives.”

5 So the servants of King Hezekiah went to Isaiah,

6 who replied, “Tell your master that this is what the LORD says: ‘Do not be afraid of the words you have heard, with which the servants of the king of Assyria have blasphemed Me.

7 Behold, I will put a spirit in him so that he will hear a rumor and return to his own land, where I will cause him to fall by the sword.’”
