Reference: Singing
Morish
In the O.T. we find there were courses of singers, and there were some who were 'taught to sing praise.' Instruments were also appointed for the singers. 1Ki 10:12. In Hab 3:19, at the end of the prophet's poetical 'prayer,' it says, "To the chief singer on my stringed instruments." "The singers went before, the players on instruments followed after; among them were the damsels playing with timbrels." Ps 68:25.
Such organised choirs have no place in the N.T. They that worship God "must worship him in spirit and in truth." This also applies to the singing: "I will sing with the spirit, and I will sing with the understanding also." 1Co 14:15: cf. 1Co 14:26. "Be filled with the Spirit, speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody or chanting in your heart to the Lord." Eph 5:19. "In psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord." Col 3:16. There will be singing in heaven. Re 5:9. Singing and PRAISE naturally go together. At the institution of the Lord's supper they 'sang a hymn,' margin 'psalm,' ?????. Mt 26:30. The same word is translated 'sang praises' unto God, when Paul and Silas were in prison, Ac 16:25; and the Lord sings praise in the midst of the assembly. Ps 22:22; Heb 2:12.
