Exodus 8:13-15

New Revised Standard Version, Anglicised

¹³ And the Lord did as Moses requested: the frogs died in the houses, the courtyards, and the fields. ¹⁴ And they gathered them together in heaps, and the land stank. ¹⁵ But when Pharaoh saw that there was a respite, he hardened his heart, and would not listen to them, just as the Lord had said.
