Charles H. Spurgeon on Psalms 78:12

Zoan. The name of a city in Egypt (Nu 13:22), though it be not set down in the story in Exodus, is twice specified by the writer of this psalm, here, and Ps 78:43, as the scene wherein the wondrous works were wrought on Pharaoh by Moses; either because really the first and principal of the miracles were shewed Pharaoh there, this city being the seat of the king, and a most ancient city, as appears by the expression used of Hebron, in Nu 13:22, where to set out the antiquity of that city, where Abraham, the tenth from Noah dwelt, it is said, that "it was built seven years before Zoan in Egypt; "or perhaps only in poetical style, as "the field" or country of Zoan, is all one with the "land of Egypt" foregoing. Thus, in other prophetic writings, when judgments are threatened, instead of "Egypt" sometimes we find "Zoan" alone, Isa 19:11, where the "princes of Zoan" are all one with the counsellors of Pharaoh; sometimes "the princes of Zoan, "with the addition of some other city, as Isa 19:13, "the princes of Zoan, the princes of Noph, "i.e., again, the counsellors of that kingdom, which as it follows, "have seduced Egypt, " —brought the whole nation to ruin. So Isa 30:4, where they sent to Egypt for relief, it is said, their "princes were at Zoan, their ambassadors at Hanes." Henry Hammond.
