'Prayer' in the Bible

Jehovah, in trouble they sought thee; they poured out their whispered prayer when thy chastening was upon them.

It may be Jehovah thy God will hear the words of Rab-shakeh, whom the king of Assyria his master has sent to reproach the living God, and will rebuke the words which Jehovah thy God hath heard. Therefore lift up a prayer for the remnant that is left.

Go and say to Hezekiah, Thus saith Jehovah, the God of David thy father: I have heard thy prayer, I have seen thy tears: behold, I will add to thy days fifteen years.

even them will I bring to my holy mountain, and make them joyful in my house of prayer; their burnt-offerings and their sacrifices shall be accepted upon mine altar: for my house shall be called a house of prayer for all the peoples.
