'Supplications' in the Bible

and I set my face unto the Lord God, to seek by prayer and supplications, with fasting, and sackcloth, and ashes.

Incline, O my God, Thine ear, and hear, open Thine eyes and see our desolations, and the city on which Thy name is called; for not for our righteous acts are we causing our supplications to fall before Thee, but for Thy mercies that are many.

at the commencement of thy supplications hath the word come forth, and I have come to declare it, for thou art greatly desired, and understand thou concerning the matter, and consider concerning the appearance.
