Exodus 11:4-6

Verse 4

About midnight will I go out - Whether God did this by the ministry of a good or of an evil angel is a matter of little importance, though some commentators have greatly magnified it. Both kinds of angels are under his power and jurisdiction, and he may employ them as he pleases. Such a work of destruction as the slaying of the first-born is supposed to be more proper for a bad than for a good angel. But the works of God's justice are not less holy and pure than the works of his mercy; and the highest archangel may, with the utmost propriety, be employed in either.
Verse 5

The first-born of Pharaoh, etc. - From the heir to the Egyptian throne to the son of the most abject slave, or the principal person in each family. See Clarke's note on Exo 12:29.

The maid-servant that is behind the mill - The meanest slaves were employed in this work. In many parts of the east they still grind all their corn with a kind of portable mill-stones, the upper one of which is turned round by a sort of lever fixed in the rim. A drawing of one of these machines as used in China is now before me, and the person who grinds is represented as pushing the lever before him, and thus running round with the stone. Perhaps something like this is intended by the expression Behind the mill in the text. On this passage Dr. Shaw has the following observation: - "Most families grind their wheat and barley at home, having two portable mill-stones for that purpose, the uppermost of which is turned round by a small handle of wood or iron that is placed in the rim. When this stone is large, or expedition required, a second person is called in to assist; and as it is usual for women alone to be concerned in this employment, who seat themselves over against each other with the mill-stone between them, we may see, not only the propriety of the expression (Exo 11:5) of sitting behind the mill, but the force of another, (Mat 24:41), that two women shall be grinding at the mill; the one shall be taken, and the other left." - Travels, p. 231, 4th edit. These portable mills, under the name of querns, were used among our ancestors in this and the sister kingdoms, and some of them are in use to the present day. Both the instrument and its name our forefathers seem to have borrowed from the continent. They have long existed among the inhabitants of Shetland, Iceland, Norway, Denmark, etc.
Verse 6

There shall be a great cry - Of the dying and for the dead. See more on this subject, Exo 12:30 (note).
