In the sight of their fathers he performed wonders in the land of Egypt, in the fields of Zoan.

PSALM 78 To comprehend many things within small compass, it is to be observed, that in this psalm there are two leading topics. On the one hand, it is declared how God adopted for himself a Church from the posterity of Abraham, how tenderly and graciously he cherished it, how wonderfully he brought it out of Egypt, and how varied were the blessings which he bestowed upon it.

Egypt, here called the field of Zoan, was the scene of marvellous things which were done in open day in the sight of Israel. These were extraordinary, upon a vast scale, astounding, indisputable, and such as ought to have rendered it impossible for an Israelite to be disloyal to Jehovah, Israel's God.

Matthew Henry Presbyterian @wholebiblehenry

In these verses, I. The psalmist observes the late rebukes of Providence that the people of Israel had been under, which they had brought upon themselves by their dealing treacherously with God, Psa 78:9-11. The children of Ephraim, in which tribe Shiloh was, though they were well armed and shot with bows, yet turned back in the day of battle.
