Sing for joy to God our strength; shout aloud to the God of Jacob!
Begin the music, strike the tambourine, play the melodious harp and lyre.
Sound the ram’s horn at the New Moon, and when the moon is full, on the day of our Feast;
this is a decree for Israel, an ordinance of the God of Jacob.
He established it as a statute for Joseph when he went out against Egypt, where we heard a language we did not understand.
He says, “I removed the burden from their shoulders; their hands were set free from the basket.
In your distress you called and I rescued you, I answered you out of a thundercloud; I tested you at the waters of Meribah.
“Hear, O my people, and I will warn you — if you would but listen to me, O Israel!
You shall have no foreign god among you; you shall not bow down to an alien god.
I am the Lord your God, who brought you up out of Egypt. Open wide your mouth and I will fill it.
Psalm 81:1-10
