Exodus 8:15

But when Pharaoh saw that there was respite ,.... From his affliction, as the Targum of Jonathan adds; the plague was removed, and he found himself and his people at ease: or there was a "breathing" F3 הרוחה "respiratio", Pagninus, Montanus, Tigurine version, Junius and Tremellius, Piscator, Drusius. ; before he and his people were so oppressed, that they could scarce breathe, but now being delivered from the judgment on them with which they were straitened, were enlarged and at liberty, and in easy circumstances: he hardened his heart; See Gill on Exodus 7:14 .

and hearkened not unto them ; to Moses and Aaron, to let the children of Israel go, as they had required, and he had promised:

as the Lord had said ; had foretold that he would not hearken to them, nor let Israel go as yet.
