Charles Ellicott Commentary Amos 6:5

"that sing idle songs to the sound of the viol; that invent for themselves instruments of music, like David;" — Amos 6:5 (ASV)

Chant.— The original Hebrew only occurs in this passage, and is best rendered prattle, or jabber. The comparison with David is ironic. He made these instruments to please the Lord, these princes to please themselves.
