Exodus 8:13-15

Wycliffe Bible

¹³ And the Lord did by the word of Moses; and the paddocks were dead from [the] houses, and from [the] towns, and from [the] fields; (And the Lord did what Moses asked; and the frogs were dead in the houses, and in the towns, and in the fields;)

¹⁴ and they gathered them into great heaps, and the land was rotten, or corrupted with stink. [and they gathered them together into great heaps without number, and the earth stank.]

¹⁵ Soothly Pharaoh saw that rest was given, and he made grievous his heart, and he heard not them, as the Lord commanded. (But when Pharaoh saw that the trouble had ceased, he hardened his heart, and he would not listen to them, as the Lord had said.)
