How he had wrought his signs in Egypt,.... The plagues which he brought upon the Egyptians, for refusing to let Israel go: and his wonders in the field of Zoan, or in the country of Zoan, that is, Tanis, as the Targum renders it; so the Septuagint and Vulgate Latin versions; see Psa 78:12, an enumeration of these signs and wonders follows; but not of all, nor in the order in which they were: only seven are mentioned, with which compare the seven vials or last plagues, Rev 6:1.
