Psalms 81:3-6

³Blow up the trumpet in the new moon, in the time appointed, on our solemn feast day.

⁴For this was a statute for Israel, and a law of the God of Jacob.

⁵This he ordained in Joseph for a testimony, when he went out through the land of Egypt: where I heard a language that I understood not.

⁶I removed his shoulder from the burden: his hands were delivered from the pots.
