In Genesis 27:33, this signifies a great alteration and change of state when one is regenerating, and comes to the point when the dominion of truth gives place to the good. (Arcana Coelestia 3593)

In Genesis 42:28, this signifies a common terror because of the permissions of Providence. (Arcana Coelestia 5502, 5503)

People in good do, indeed, tremble at the presence of the Divine, but it is a holy tremor before they receive divine goodness. (Arcana Coelestia 8816)

In Psalm 55:5, this signifies distress felt in temptations. (Apocalypse Explained 282[6])

'To tremble,' as in Jeremiah 10:10, relates to the church when falsities are believed and called truths.

'To tremble' or 'to be amazed,' as in Ezekiel 26:15-18, signifies a complete change of state.

3593. 'And Isaac trembled very greatly' means the great change that accompanied the inversion of state. This is clear from the meaning of 'trembling' as a change that took place. Its accompanying the inversion of state is evident from what has been stated above about the two states a person passes through when being regenerated - the state before he has been regenerated and the state after. That is to say, in the state before he has been regenerated truths apparently have dominion, but in the state after he has been regenerated, truths give way and good acquires dominion - see what has often been shown already, in 1904, 2063, 2189, 2697, 2979, 3286, 3288, 3310 (end), 3325, 3330, 3332, 3336, 3470, 3509, 3539, 3548, 3556, 3563, 3570, 3576, 3579.
