Psalms 81:5-9

⁵a witness he set up in Joseph, when he marched against Egypt's land, where he heard an unknown voice say:

⁶“I removed from your shoulder the burden, and freed your hands from the basket.

⁷At your call of distress I delivered you, from the thundercloud I answered you. At Meribah's waters I tested you. Selah

⁸“Listen, my people, to my warning, O Israel, if you would but listen!

⁹There must not be a strange god amongst you, you must bow to no foreign god.
