4 And Moses said, Thus saith Jehovah, About midnight will I go out into the midst of Egypt: 5 and all the first-born in the land of Egypt shall die, from the first-born of Pharaoh that sitteth upon his throne, even unto the first-born of the maid-servant that is behind the mill; and all the first-born of cattle. 6 And there shall be a great cry throughout all the land of Egypt, such as there hath not been, nor shall be any more. 7 But against any of the children of Israel shall not a dog move his tongue, against man or beast: that ye may know how that Jehovah doth make a distinction between the Egyptians and Israel. 8 And all these thy servants shall come down unto me, and bow down themselves unto me, saying, Get thee out, and all the people that follow thee: and after that I will go out. And he went out from Pharaoh in hot anger. 9 And Jehovah said unto Moses, Pharaoh will not hearken unto you; that my wonders may be multiplied in the land of Egypt. 10 And Moses and Aaron did all these wonders before Pharaoh: and Jehovah hardened Pharaoh's heart, and he did not let the children of Israel go out of his land.

Commentary on Exodus 11:4-10
(Read Exodus 11:4-10)
The death of all the first-born in Egypt at once: this plague had been the first threatened, but is last executed. See how slow God is to wrath. The plague is foretold, the time is fixed; all their first-born should sleep the sleep of death, not silently, but so as to rouse the families at midnight. The prince was not too high to be reached by it, nor the slaves at the mill too low to be noticed. While angels slew the Egyptians, not so much as a dog should bark at any of the children of Israel. It is an earnest of the difference there shall be in the great day, between God's people and his enemies. Did men know what a difference God puts, and will put to eternity, between those that serve him and those that serve him not, religion would not seem to them an indifferent thing; nor would they act in it with so much carelessness as they do. When Moses had thus delivered his message, he went out from Pharaoh in great anger at his obstinacy; though he was the meekest of the men of the earth. The Scripture has foretold the unbelief of many who hear the gospel, that it might not be a surprise or stumbling-block to us, Romans 10:16. Let us never think the worse of the gospel of Christ for the slights men put upon it. Pharaoh was hardened, yet he was compelled to abate his stern and haughty demands, till the Israelites got full freedom. In like manner the people of God will find that every struggle against their spiritual adversary, made in the might of Jesus Christ, every attempt to overcome him by the blood of the Lamb, and every desire to attain increasing likeness and love to that Lamb, will be rewarded by increasing freedom from the enemy of souls.
