'Pray' in the Bible

Is any among you afflicted? let him pray. Is any merry? let him sing psalms.

Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord:

Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much.
