Psalms 81:7

⁵ He ordained it as a testimony for Joseph when he went out over the land of Egypt, where I heard an unfamiliar language:

⁶ “I relieved his shoulder of the burden; his hands were freed from the basket.

You called out in distress, and I rescued you; I answered you from the cloud of thunder; I tested you at the waters of Meribah. Selah

⁸ Hear, O My people, and I will warn you: O Israel, if only you would listen to Me!

⁹ There must be no strange god among you, nor shall you bow to a foreign god.

Do read the surrounding verses too, because the context often says more than a single verse.
