God had done great things for them, and yet they revolted from him and rebelled against him (v. 20): Of old time I have broken thy yoke and burst thy bonds; this refers to the bringing of them out of the land of Egypt and the house of bondage, which they would not remember (v. 6), but God did; for, when he told them that they should have no other gods before him, he prefixed this as a reason: I am the Lord thy God that brought thee out of the land of Egypt! These bonds of theirs which God had loosed should have bound them for ever to him; but they had ungratefully broken the bonds of duty to that God who had broken the bonds of their slavery.
