'Prayer' in the Bible

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

Now therefore, O our God, hearken unto the prayer of thy servant, and to his supplications, and cause thy face to shine upon thy sanctuary that is desolate, for the Lord's sake.

yea, while I was speaking in prayer, the man Gabriel, whom I had seen in the vision at the beginning, being caused to fly swiftly, touched me about the time of the evening oblation.
