'Prayer' in the Bible

Please, let your ear be attentive and your eyes open to hear the prayer of your servant that I am praying before you by day and by night for your servants, the {Israelites}, and confessing the sins of the {Israelites} that we have sinned against you. I and my father's house have sinned.

O Lord, please let your ear be attentive to the prayer of your servant and to the prayer of your servants who delight to revere in your name. Please, let your servant be successful this day and give him compassion before this man." I was cupbearer for the king.

Mattaniah son of Micah, son of Zabdi, son of Asaph, [who was] the leader to begin the thanksgiving prayer, and Bakbukiah the second of his brothers; Abda son of Shammua, son of Galal, son of Jeduthun.
