Isaiah 37:5 KJV

3And they said unto him, Thus saith Hezekiah, This day is a day of trouble, and of rebuke, and of blasphemy: for the children are come to the birth, and there is not strength to bring forth.

4It may be the LORD thy God will hear the words of Rabshakeh, whom the king of Assyria his master hath sent to reproach the living God, and will reprove the words which the LORD thy God hath heard: wherefore lift up thy prayer for the remnant that is left.

5So the servants of king Hezekiah came to Isaiah.

6And Isaiah said unto them, Thus shall ye say unto your master, Thus saith the LORD, Be not afraid of the words that thou hast heard, wherewith the servants of the king of Assyria have blasphemed me.

7Behold, I will send a blast upon him, and he shall hear a rumour, and return to his own land; and I will cause him to fall by the sword in his own land.
