15 The leech has two daughters , "Give ," "Give ." There are three things that will not be satisfied , Four that will not say , "Enough ": 16 Sheol , and the barren womb , Earth that is never satisfied with water , And fire that never says , "Enough ."
Matthew Henry's Commentary on Proverbs 30:15-16
Commentary on Proverbs 30:15-17
(Read Proverbs 30:15-17)
Cruelty and covetousness are two daughters of the horseleech, that still cry, "Give, give," and they are continually uneasy to themselves. Four things never are satisfied, to which these devourers are compared. Those are never rich that are always coveting. And many who have come to a bad end, have owned that their wicked courses began by despising their parents' authority.
