Psalms 81:4

2 Take a psalm, and bring hither the timbrel, the pleasant harp with the psaltery.

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

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

5 This 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.

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

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
