"To the chief Musician upon (a) Gittith, [A Psalm] of Asaph." Sing (b) aloud unto God our strength: make a joyful noise unto the God of Jacob.
(a) An instrument of music brought from Geth.
(b) It seems that this psalm was appointed for solemn feasts and assemblies of the people to whom for a time these ceremonies were ordained, but now under the gospel are abolished.
