'Prayer' in the Bible

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

Turn back, and say to Hezekiah the prince of my people, Thus saith Jehovah, the God of David thy father, I have heard thy prayer, I have seen thy tears: behold, I will heal thee; on the third day thou shalt go up unto the house of Jehovah.
