'Prayer' in the Bible

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

Now therefore, our God, listen to (heed) the prayer of Your servant (Daniel) and his supplications, and for Your own sake let Your face shine on Your desolate sanctuary.

while I was still speaking in prayer and extremely exhausted, the man Gabriel, whom I had seen in the earlier vision, came to me about the time of the evening sacrifice.
