Exodus 11:7 - Exposition

Shall not a dog move his tongue . So far from a sudden destruction coming upon them, there shall not so much as a dog bark at them- They shall incur no hurt—no danger. (Compare Joshua 10:21 .) That ye may know how that the Lord doth put a difference — i.e; "that both ye courtiers and all Egypt may know how great a difference God puts between us—his peculiar people-and you wretched idolaters."
