'Prayer' in the Bible

Let thine ear now be attentive, and thine eyes open, that thou mayest hearken unto the prayer of thy servant, which I pray before thee at this time, day and night, for the children of Israel thy servants while I confess the sins of the children of Israel, which we have sinned against thee. Yea, I and my father's house have sinned:

O Lord, I beseech thee, let now thine ear be attentive to the prayer of thy servant, and to the prayer of thy servants, who delight to fear thy name; and prosper, I pray thee, thy servant this day, and grant him mercy in the sight of this man. Now I was cupbearer to the king.

But we made our prayer unto our God, and set a watch against them day and night, because of them.

and Mattaniah the son of Mica, the son of Zabdi, the son of Asaph, who was the chief to begin the thanksgiving in prayer, and Bakbukiah, the second among his brethren; and Abda the son of Shammua, the son of Galal, the son of Jeduthun.
