Proverbs 30:15

The horseleech, an insatiable creature, sucking blood till it be ready to burst, hath two daughters; which are either,

1. The two forks into which her tongue is divided, and wherewith she sucks: but those who have more accurately observed and described the frame of that creature tell us that they have no tongue, and that they suck either by three little teeth, or several parts of the mouth gathered and compressed together. Or rather,

2. The following things, which resemble the horse leech in its insatiableness; nothing being more ordinary than to call those persons or things the sons or daughters of those whose examples they imitate. And whereas it is objected, that they are not only two, but three, yea, four, as is said in the next clause, the answer is easy, that though he begin with two, yet he proceeds from thence to three, and four, all which are said to be the daughters of the horseleech, if the words be rendered commodiously, and as they are in the Hebrew, as we shall presently see. Crying, Give, give; never filled, and always craving, and ready to receive more and more. There are three things; or, yea, (which may be understood in this, as it is in our translation of the next clause,) they (to wit, the daughters of the horseleech) are three; that are never satisfied; which is added partly to explain the former clause, Give, give, and to show the cause of that excessive desire of more, because they were not contented with what they had; and partly to give the reason why he calls them the daughters of the horseleech. Yea, four things say not; or, yea, they (the daughters forementioned) are four, which say not.
