Isaiah 64:3 Meaning and Commentary

Isaiah 64:3

When thou didst terrible things, which we looked not for, thou
camest down
Referring to the wonderful things God did in Egypt, at the Red sea, and in the wilderness, and particularly at Mount Sinai, things that were unexpected, and not looked for; then the Lord came down, and made visible displays of his power and presence, especially on Mount Sinai; see ( Exodus 19:18 ) : the mountains flowed down at thy presence;
not Sinai only, but others also; Kimchi says Seir and Paran; ( Judges 5:4 Judges 5:5 ) ( Psalms 68:7 Psalms 68:8 ) ( Habakkuk 3:3 Habakkuk 3:6 ) .

Isaiah 64:3 In-Context

1 Tear open the skies and come down to earth so that the mountains will tremble before you.

2 Like a fire that burns twigs, like a fire that makes water boil, let your enemies know who you are. Then all nations will shake with fear when they see you.

3 You have done amazing things we did not expect. You came down, and the mountains trembled before you.

4 From long ago no one has ever heard of a God like you. No one has ever seen a God besides you, who helps the people who trust you.

5 You help those who enjoy doing good, who remember how you want them to live. But you were angry because we sinned. For a long time we disobeyed, so how can we be saved?
