'Supplication' in the Bible

The LORD hath heard my supplication; the LORD will receive my prayer.

I cried to thee, O LORD; and unto the LORD I made supplication.

{To the chief Musician on Neginoth, Maschil, A Psalm of David.} Give ear to my prayer, O God; and hide not thyself from my supplication.

Let my supplication come before thee: deliver me according to thy word.

{Maschil of David; A Prayer when he was in the cave.} I cried unto the LORD with my voice; with my voice unto the LORD did I make my supplication.
