Isaiah 37:5-7, 14-17, 27,36-38 The king prayed to the true Living God and The Lord delivered his people but before he prayed he received confirmation from Isaiah the king of Assyria was going to be kill but this this the power of prayer the king Hezekiah ran to God when he felt weak and The Lord killed the king of Assyria by his own sons just as Isaiah mention he was killed by the sword.
