Psalms 81:6,7

I removed his shoulder That is, the shoulder of my people; from the burden I delivered them from the burdensome slavery of Egypt. His hands were delivered from the pots Hebrew, מדוד תעברנה, his hands passed from the pots, or, as Chandler renders it, his hands from the pots, through which they had passed. Thus God reminds Israel of their redemption, by his mercy and power, from the burdens and drudgery imposed on them in Egypt. And from this verse to the end of the Psalm, it is evident God is the speaker. Thou calledst in trouble At the Red sea, Exodus 14:10; and I delivered thee In an unexpected and extraordinary way, and disappointed the designs of thy enemies. I answered thee in the secret place of thunder From the dark and cloudy pillar, whence I thundered and fought against the Egyptians: see Exodus 13:21; and Exodus 14:19; Exodus 14:24. Some refer this to the thunder at Sinai; but at that time they were not in trouble, but in a safe and glorious condition. Be assured, reader, that God is as ready, at all times, to hear the prayers and relieve the distresses of his people, as he was when the Israelites cried unto him in Egypt, and in the wilderness, and received answers from the cloudy pillar. Believe this, and apply to him in thy troubles.
