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 Oh that thou wouldest rend the heavens, that thou wouldest come down, that the mountains might quake at thy presence,

2 as when fire kindleth the brushwood, [and] the fire causeth the waters to boil; to make thy name known to thine adversaries, that the nations may 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 For from of old men have not heard, nor perceived by the ear, neither hath the eye seen a God besides thee, who worketh for him that waiteth for him.

5 Thou meetest him that rejoiceth and worketh righteousness, those that remember thee in thy ways: behold, thou wast wroth, and we sinned: in them [have we been] of long time; and shall we be saved?
