'Supplication' in the Bible

The Lord has heard my supplication,The Lord receives my prayer.

Blessed be the Lord,Because He has heard the voice of my supplication.

To You, O Lord, I called,And to the Lord I made supplication:

For the choir director; on stringed instruments. A Maskil of David.Give ear to my prayer, O God;And do not hide Yourself from my supplication.

Let my supplication come before You;Deliver me according to Your word.

Maskil of David, when he was in the cave. A Prayer.I cry aloud with my voice to the Lord;I make supplication with my voice to the Lord.
