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 If only You would rend the heavens and come down, so that mountains would quake at Your presence,

2 as fire kindles the brushwood and causes the water to boil, to make Your name known to Your enemies, so that the nations will tremble at Your presence!

3 When You did awesome works that we did not expect, You came down, and the mountains trembled at Your presence.

4 From ancient times no one has heard, no ear has perceived, no eye has seen any God besides You, who acts on behalf of those who wait for Him.

5 You welcome those who gladly do right, who remember Your ways. Surely You were angry, for we sinned. How can we be saved if we remain in our sins?
