Exodus 14:20

“And it came between the camp of the Egyptians and the camp of Israel, etc.] That is, the pillar of cloud, and the Angel of God, or Jehovah, in it, whereby the camp of Israel was secured from being annoyed by the camp of the Egyptians; and was an emblem of the gracious interposition of Christ between his spiritual Israel, whom he has redeemed by his blood, and their spiritual enemies, the Egyptians, the men of the world that hate them, from whose rage and malice Christ is their protection and safeguard: and it was a cloud and darkness [to them]; to the Egyptians; it cast a shade upon them, and made the darkness of the night still greater to them, so that they could not see their way, and knew…”

“Psa 18:11; Pro 4:18, Pro 4:19; Isa 8:14; Co2 2:15, Co2 2:16 Exodus 14:21”

“"And it was the cloud and the darkness (sc., to the Egyptians), and lighted up the night (sc., to the Israelites)." Fuit nubes partim lucida et partim tenebricosa, ex una parte tenebricosa fuit Aegyptiis, ex altera lucida Israelitis (Jonathan). Although the article is striking in והחשׁך, the difficulty is not to be removed, as Ewald proposes, by substituting והחשׁך, "and as for the cloud, it caused darkness;" for in that case the grammar would require the imperfect with ו consec. This alteration of the text is also rendered suspicious from the fact that both Onkelos and the lxx read and render the word as a substantive. Exodus 14:21”
