Praise the LORD with harp: sing unto him with the psaltery and an instrument of ten strings.

Augustine of Hippo
AD 430
2. "Praise the Lord with harp:" praise the Lord, presenting unto Him your bodies a living sacrifice. "Sing unto Him with the psaltery for ten strings" (ver. 2): let your members be servants to the love of God, and of your neighbour, in which are kept both the three and the seven commandments.
Psaltery. Hebrew nebel, (Haydock) which does not resemble the modern psaltery. (Calmet)
We must carefully observe mortification, and the decalogue. (Worthington)
