4 Else, if thou refuse to let my people go, behold, to morrow will I bring the locusts into thy coast: 5 And they shall cover the face [1] of the earth, that one cannot be able to see the earth: and they shall eat the residue of that which is escaped, which remaineth unto you from the hail, and shall eat every tree which groweth for you out of the field: 6 And they shall fill thy houses, and the houses of all thy servants, and the houses of all the Egyptians; which neither thy fathers, nor thy fathers' fathers have seen, since the day that they were upon the earth unto this day. And he turned himself, and went out from Pharaoh.
4 If you refuse to let them go, I will bring locusts into your country tomorrow. 5 They will cover the face of the ground so that it cannot be seen. They will devour what little you have left after the hail, including every tree that is growing in your fields. 6 They will fill your houses and those of all your officials and all the Egyptians-something neither your parents nor your ancestors have ever seen from the day they settled in this land till now.' " Then Moses turned and left Pharaoh.
4 For if you refuse to let my people go, behold, tomorrow I will bring locusts into your country, 5 and they shall cover the face of the land, so that no one can see the land. And they shall eat what is left to you after the hail, and they shall eat every tree of yours that grows in the field, 6 and they shall fill your houses and the houses of all your servants and of all the Egyptians, as neither your fathers nor your grandfathers have seen, from the day they came on earth to this day.'" Then he turned and went out from Pharaoh.
4 If you refuse to release my people, watch out; tomorrow I'm bringing locusts into your country. 5 They'll cover every square inch of ground; no one will be able to see the ground. They'll devour everything left over from the hailstorm, even the saplings out in the fields - they'll clear-cut the trees. 6 And they'll invade your houses, filling the houses of your servants, filling every house in Egypt. Nobody will have ever seen anything like this, from the time your ancestors first set foot on this soil until today.'" Then he turned on his heel and left Pharaoh.
4 Or else, if you refuse to let My people go, behold, tomorrow I will bring locusts into your territory. 5 And they shall cover the face of the earth, so that no one will be able to see the earth; and they shall eat the residue of what is left, which remains to you from the hail, and they shall eat every tree which grows up for you out of the field. 6 They shall fill your houses, the houses of all your servants, and the houses of all the Egyptians--which neither your fathers nor your fathers' fathers have seen, since the day that they were on the earth to this day.' " And he turned and went out from Pharaoh.
4 If you refuse, watch out! For tomorrow I will bring a swarm of locusts on your country. 5 They will cover the land so that you won't be able to see the ground. They will devour what little is left of your crops after the hailstorm, including all the trees growing in the fields. 6 They will overrun your palaces and the homes of your officials and all the houses in Egypt. Never in the history of Egypt have your ancestors seen a plague like this one!" And with that, Moses turned and left Pharaoh.
Matthew Henry's Commentary on Exodus 10:4-6
Commentary on Exodus 10:1-11
(Read Exodus 10:1-11)
The plagues of Egypt show the sinfulness of sin. They warn the children of men not to strive with their Maker. Pharaoh had pretended to humble himself; but no account was made of it, for he was not sincere therein. The plague of locusts is threatened. This should be much worse than any of that kind which had ever been known. Pharaoh's attendants persuade him to come to terms with Moses. Hereupon Pharaoh will allow the men to go, falsely pretending that this was all they desired. He swears that they shall not remove their little ones. Satan does all he can to hinder those that serve God themselves, from bringing their children to serve him. He is a sworn enemy to early piety. Whatever would put us from engaging our children in God's service, we have reason to suspect Satan in it. Nor should the young forget that the Lord's counsel is, Remember thy Creator in the days of thy youth; but Satan's counsel is, to keep children in a state of slavery to sin and to the world. Mark that the great foe of man wishes to retain him by the ties of affection, as Pharaoh would have taken hostages from the Israelites for their return, by holding their wives and children in captivity. Satan is willing to share our duty and our service with the Saviour, because the Saviour will not accept those terms.
