Eph 5:19.   Speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord; Jas 5:13.   Is any among you afflicted? let him pray. Is any merry? let him sing psalms. 1 Cor 14:15.   What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also.
