C. F. Keil and Franz Delitzsch on Exodus 14:20

Exo 14:20

“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.
