Exodus 8:11-14

11The frogs will leave you and your houses, your officials and your people; they will remain only in the Nile.” 12After Moses and Aaron left Pharaoh, Moses cried out to the LORD about the frogs he had brought on Pharaoh. 13And the LORD did what Moses asked. The frogs died in the houses, in the courtyards and in the fields. 14They were piled into heaps, and the land reeked of them.
