The Division.

Exodus 8:23 (KJV)

23 And I will put a division between my people and thy people: to morrow shall this sign be.

And I will put a division. 

A redemption; so Luke 1:68. Aristotle reporteth that, when from the hill Etna there ran down a torrent of fire that consumed all the houses thereabouts, in the midst of those fearful flames the river of fire parted itself, and made a kind of lane for those who ventured to rescue their aged parents. This extorted from him an acknowledgment of God’s good providence for the godly here on earth.
