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. 1 Kings 10:12 . In Habakkuk 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." Psalm 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." 1 Corinthians 14:15 : cf. 1 Corinthians 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." Ephesians 5:19 . "In psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord." Colossians 3:16 . There will be singing in heaven. Revelation 5:9 . Singing and PRAISE naturally go together. At the institution of the Lord's supper they 'sang a hymn,' margin 'psalm,' ὑμνέω. Matthew 26:30 . The same word is translated 'sang praises' unto God, when Paul and Silas were in prison, Acts 16:25; and the Lord sings praise in the midst of the assembly. Psalm 22:22; Hebrews 2:12 .
