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 O that thou wouldst rend the heavens and come down, that the mountains might quake at thy presence--

2 as when fire kindles brushwood and the fire causes water to boil--to make thy name known to thy adversaries, and that the nations might tremble at thy presence!

3 When thou didst terrible things which we looked not for, thou camest down, the mountains quaked at thy presence.

4 From of old no one has heard or perceived by the ear, no eye has seen a God besides thee, who works for those who wait for him.

5 Thou meetest him that joyfully works righteousness, those that remember thee in thy ways. Behold, thou wast angry, and we sinned; in our sins we have been a long time, and shall we be saved?
