John Trapp on Isaiah 19:3

Ver. 3. And the ſpirit of Egypt ſhall fail] Fail and falter; their wits ſhall not ſerve them, but be drained and emptied, as the Hebrew word here ſignifieth. By ſpirit here underſtand their Wiſdom, Learning and Sharpneſs, for the which they were famous among, and frequented by other Nations. Moſes was skilled in their Learning, Acts 7.23. Pythagoras, Plato, Solon, Anaxagoras, and other Philoſophers gat much by them. Mercurius Triſmegiſt ſaith of Egypt, that it was the Image of Heaven, Aug. de C. D. lib. 8. cap. 14. and the Temple of the whole world. By spirit here, ſome underſtand their familiar ſpirits. See Levit. 19.31.

And they ſhall ſeek to the Idols] Whereof they had great ſtore (ſo that they were derided by other Idolaters) but their chief Deity was Latona, ſaith Herodotus.

And to the charmers] Who have their name in Hebrew from their low or ſlow ſpeaking.
