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 flow down at thy presence,
2 -- as fire kindleth brushwood, as the fire causeth water to boil, to make thy name known to thine adversaries, that the nations might tremble at thy presence!
3 When thou didst terrible things [which] we looked not for, thou camest down, and the mountains flowed down at thy presence.
4 Never have [men] heard, nor perceived by the ear, nor hath eye seen a God beside thee, who acteth for him that waiteth for him.
5 Thou meetest him that rejoiceth to do righteousness, those that remember thee in thy ways: (behold, thou wast wroth, and we have sinned:) in those is perpetuity, and we shall be saved.
