'Prayer' in the Bible

It may be the LORD thy God will hear all 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 are left.

Turn again, and tell Hezekiah the captain of my people, Thus saith the LORD, 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 the LORD.
