Psalms 81:1-4

MKJV(i) 1 To the Chief Musician. On Gittith, A Psalm of Asaph. Sing aloud to God our strength; shout for joy to the God of Jacob. 2 Lift up a psalm, and bring the timbrel here, the pleasing lyre and harp. 3 Blow the ram's horn in the new moon, in the time appointed, on our solemn feast day. 4 For this was a Precept for Israel, an ordinance of the God of Jacob.
