Charles H. Spurgeon on Psalms 78:43

How he had wrought his signs in Egypt. The plagues were ensigns of Jehovah's presence and proofs of his hatred of idols; these instructive acts of power were wrought in the open view of all, as signals are set up to be observed by those far and near. And his wonders in the field of Zoan. In the whole land were miracles wrought, not in cities alone, but in the broad territory, in the most select and ancient regions of the proud nation. This the Israelites ought not to have forgotten, for they were the favoured people for whom these memorable deeds were wrought.
