EXPOSITION
The fourth plague moves the Pharaoh more than any preceding one. He still cannot bring himself to grant the demand of Moses; but he offers a compromise. The Israelites shall have a respite from their toils, and be permitted to hold their festival, and offer the needful sacrifices in Egypt (Exodus 8:25). When this offer is for good reasons not accepted, he yields even further—he will let the people go and sacrifice in the wilderness—only they must not "go far away"(Exodus 8:28). Having made this promise, he obtains for the second time the intercession of Moses and the discontinuance of the plague in consequence of it. But then, as before, when he saw that there was respite (Exodus 8:15), he retracted his promise, hardened himself, and refused to allow the people to quit Egypt (Exodus 8:32).
