Psalms 106: 6 - 7, 13 - 14, 21 - 23
6 Both we and our fathers have sinned; we have committed iniquity, we have done wickedly.
7 Our fathers, when they were in Egypt, did not consider thy wonderful works; they did not remember the abundance of thy steadfast love, but rebelled against the Most High at the Red Sea.
13 But they soon forgot his works; they did not wait for his counsel.
14 But they had a wanton craving in the wilderness, and put God to the test in the desert;
21 They forgot God, their Savior, who had done great things in Egypt,
22 wondrous works in the land of Ham, and terrible things by the Red Sea.
23 Therefore he said he would destroy them -- had not Moses, his chosen one, stood in the breach before him, to turn away his wrath from destroying them.
