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.

4. to-morrow will I bring the locusts—Moses was commissioned to renew the request, so often made and denied, with an assurance that an unfavorable answer would be followed on the morrow by an invasion of locusts. This species of insect resembles a large, spotted, red and black, double-winged grasshopper, about three inches or less in length, with the two hind legs working like hinged springs of immense strength and elasticity. Perhaps no more terrible scourge was ever brought on a land than those voracious insects, which fly in such countless numbers as to darken the land which they infest; and on whatever place they alight, they convert it into a waste and barren desert, stripping the ground of its verdure, the trees of their leaves and bark, and producing in a few hours a degree of desolation which it requires the lapse of years to repair.
