Deuteronomy 9:7

Remember and forget not how thou provokedst the Lord, thy God, to wrath in the wilderness, their rebelliousness had been a constant challenge to the wrath of God; from the day that thou didst depart out of the land of Egypt until ye came unto this place ye have been rebellious against the Lord. It was an unsparing censure, a sharp reproof, for it was necessary that the people feel the heinousness of their sin, in order to remain in the fellowship of the Lord in proper humility.
