Psalms 81:3-8

³Blow the trumpet on the day of the new moon, on the day of the full moon, when our feast day begins.

⁴For it is a statute for Israel, a decree given by the God of Jacob.

⁵He issued it as a regulation in Joseph when he went against the land of Egypt, where I heard a voice that I did not recognize:

⁶“I removed the burden from his shoulder; his hands were freed from holding the basket.

⁷In your distress you called out, and I helped you; I answered you from a dark thundercloud. I tested you at the waters of Meribah. Selah

⁸Listen, my people, for I will warn you, Israel, if you would only listen to me!
