How could Moses change God’s mind? (Psalm 106:23)

19 
At Horeb they made a calf
    and worshiped an idol cast from metal.
20 
They exchanged their glorious God
    for an image of a bull, which eats grass.
21 
They forgot the God who saved them,
    who had done great things in Egypt,
22 
miracles in the land of Ham
    and awesome deeds by the Red Sea.
23 
So he said he would destroy them—
    had not Moses, his chosen one,
stood in the breach before him
    to keep his wrath from destroying them.
