'Prayer' in the Bible

And he gave him the copy of the order which had been given out in Shushan for their destruction, ordering him to let Esther see it, and to make it clear to her; and to say to her that she was to go in to the king, requesting his mercy, and making prayer for her people.

And while they were drinking wine the king said to Esther, What is your prayer? for it will be given to you and what is your request? for it will be done, even to the half of my kingdom.

Then Esther said in answer, My prayer and my request is this:

If I have the king's approval, and if it is the king's pleasure to give me my prayer and do my request, let the king and Haman come to the feast which I will make ready for them, and tomorrow I will do as the king has said.

And the king said to Esther again on the second day, while they were drinking, What is your prayer, Queen Esther? for it will be given to you; and what is your request? for it will be done, even to the half of my kingdom.

Then Esther the queen, answering, said, If I have your approval, O king, and if it is the king's pleasure, let my life be given to me in answer to my prayer, and my people at my request:

And the king in his wrath got up from the feast and went into the garden: and Haman got to his feet to make a prayer for his life to Esther the queen: for he saw that the king's purpose was evil against him.

And the king said to Esther the queen, The Jews have put five hundred men to death in Shushan, as well as the ten sons of Haman: what then have they done in the rest of the kingdom! Now what is your prayer? for it will be given to you; what other request have you? and it will be done.
