Psalms 81:5
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. 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.
The psalm recounts the blessings God gave His people and their poor response to them. It explains that Israel was scattered because they forgot God. The people also failed to acknowledge Him. They failed to heed Him. This stands as a warning because the churches in the land are forgetting Him today.
