Charles H. Spurgeon on Psalms 81:6

I removed his shoulder from the burden. Israel was the drudge and slave of Egypt, but God gave him liberty. It was by God alone that the nation was set free. Other peoples owe their liberties to their own efforts and courage, but Israel received its Magna Charta as a free gift of divine power. Truly may the Lord say of everyone of his freed men, I removed his shoulder from the burden. His hands were delivered from the pots. He was no longer compelled to carry earth, and mould it, and bake it; the earth basket was no more imposed upon the people, nor the tale of bricks exacted, for they came out into the open country where none could exact upon them. How typical all this is of the believer's deliverance from legal bondage, when, through faith, the burden of sin glides into the Saviour's sepulchre, and the servile labours of self righteousness come to an end for ever.
