Exodus 8:23-32

23 And I will put a difference between my people and thy people, and on the morrow shall this be on the land. And the Lord did thus.
24 And the dog-fly came in abundance into the houses of Pharao, and into the houses of his servants, and into all the land of Egypt; and the land was destroyed by the dog-fly.
25 And Pharao called Moses and Aaron, saying, Go and sacrifice to the Lord your God in the land.
26 And Moses said, It cannot be so, for we shall sacrifice to the Lord our God the abominations of the Egyptians; for if we sacrifice the abominations of the Egyptians before them, we shall be stoned.
27 We will go a journey of three days into the wilderness, and we will sacrifice to the Lord our God, as the Lord said to us.
28 And Pharao said, I let you go, and do ye sacrifice to your God in the wilderness, but do not go very far away: pray then for me to the Lord.
29 And Moses said, I then will go forth from thee and pray to God, and the dog-fly shall depart both from thy servants, and from thy people to-morrow. Do not thou, Pharao, deceive again, so as not to send the people away to do sacrifice to the Lord.
30 And Moses went out from Pharao, and prayed to God.
31 And the Lord did as Moses said, and removed the dog-fly from Pharao, and from his servants, and from his people, and there was not one left.
32 And Pharao hardened his heart, even on this occasion, and he would not send the people away.

Exodus 8:23-32 Meaning and Commentary

INTRODUCTION TO EXODUS 8

In this chapter Pharaoh is threatened with the plague of frogs, in case he refused to let Israel go, which accordingly was brought upon him, Ex 8:1-6 and though the magicians did something similar to it, yet these were so troublesome to Pharaoh, that he promised to let the people go, and sacrifice to God, if they removed; and a time being fixed for the removal of them, it was accordingly done at the entreaty of Moses and Aaron, Ex 8:7-14 but there being a respite, Pharaoh's heart was hardened, and the plague of lice is ordered, and which was executed; and though this the magicians essayed to do, and could not, but owned it to be the finger of God, yet Pharaoh's heart was hardened, Ex 8:15-19 wherefore he is threatened with a swarm of flies, which should not infest Goshen, only the places where the Egyptians dwelt, and it was so, Ex 8:20-24 upon which Pharaoh called for Moses, and declared himself willing the people would sacrifice in the land; but this not being satisfactory, he agreed they should go into the wilderness, but not so far; and on the account of the entreaty of Moses, the plague was removed; but still Pharaoh's heart was hardened, and he would not let the people go, Ex 8:25-32.
