'Supplications' in the Bible

So I gave my attention to the Lord God to seek Him by prayer and supplications, with fasting, sackcloth and ashes.

So now, our God, listen to the prayer of Your servant and to his supplications, and for Your sake, O Lord, let Your face shine on Your desolate sanctuary.

O my God, incline Your ear and hear! Open Your eyes and see our desolations and the city which is called by Your name; for we are not presenting our supplications before You on account of any merits of our own, but on account of Your great compassion.

At the beginning of your supplications the command was issued, and I have come to tell you, for you are highly esteemed; so give heed to the message and gain understanding of the vision.
