Deuteronomy 11:3

And his miracles, and his acts, which he did in the midst of
Egypt
The miraculous works done there, the ten plagues inflicted on the Egyptians for refusing to let Israel go:

unto Pharaoh king, of Egypt, and unto all his land;
for those plagues not only affected him and his court, and his metropolis, but all parts of the land, the inhabitants of it everywhere.
