John Gill Commentary Joshua 24:5

"And I sent Moses and Aaron, and I plagued Egypt, according to that which I did in the midst thereof: and afterward I brought you out." — Joshua 24:5 (ASV)

I sent Moses also and Aaron
To demand Israel's dismission of Pharaoh, king of Egypt, and to be the deliverers of them:

and I plagued Egypt according to that which I did amongst them ;
inflicting ten plagues upon them for refusing to let Israel go:

and afterwards I brought you out ;
that is, out of Egypt, with an high hand, and outstretched arm.
