'Supplications' in the Bible

And they said to him, Why do the disciples of John fast often and make supplications, in like manner those also of the Pharisees, but thine eat and drink?

I exhort therefore, first of all, that supplications, prayers, intercessions, thanksgivings be made for all men;

Now she who is a widow indeed, and is left alone, has put her hope in God, and continues in supplications and prayers night and day.

I am thankful to God, whom I serve from my forefathers with pure conscience, how unceasingly I have the remembrance of thee in my supplications night and day,

Who in the days of his flesh, having offered up both supplications and entreaties to him who was able to save him out of death, with strong crying and tears; (and having been heard because of his piety;)

because the eyes of the Lord are on the righteous, and his ears towards their supplications; but the face of the Lord is against them that do evil.
