Exodus 8:26-28 Tree of Life Version (TLV)
26 Then Moses went out from Pharaoh and prayed to Adonai. 27 Adonai acted according to the word of Moses, and removed the swarm of flies from Pharaoh, from his servants and from his people. Nothing remained. 28 But Pharaoh hardened his heart this time also, and did not let the people go.
