is brother to him that is a great waster: a prodigal man, who spends his substance in riotous living: the sluggard and the prodigal are brethren in iniquity; for, though they take different courses, they are both sinful, and issue in the same manner; both bring to poverty and want.

The Hithpa. התרפּה signifies here, as at Proverbs 24:10, to show oneself slack, lazy, negligent. מלאכה is properly a commission for another, as a king has a messenger, ambassador, commissioner to execute it; here, any business, whether an undertaking in commission from another, or a matter one engages in for himself. He who shows himself slack therein, produces in his way, viz., by negligence, destruction, as truly as the בּעל משׁחית, who does it directly by his conduct. Thus one is named, who is called, or who has his own delight in it, to destroy or overthrow. Jerome, incorrectly limiting: sua opera dissipantis. Hitzig well compares Matthew 12:30. In the variation, Proverbs 28:24, the destroyer is called אישׁ משׁחית, the connection of the words being adject.; on the contrary, the connection of בעל משׁחית is genit. (cf. Proverbs 22:24; Proverbs 23:2, etc.), for משׁחית as frequently means that which destroys = destruction. Von Hofmann (Schriftbew. ii. 2, 403) understands 'אישׁ מ of the street robber, 'בעל מ of the captain of robbers; but the designation for the latter must be 'שׂר מ, though at 1-Kings 11:24 he is called by the name שׂר גּדוּד. The form of the word in the proverb here is more original than at 38:24. There חבר [companion] is used, here אח [brother], a general Semitic name of him who, or of that which, is in any way related to another, cf. Job 30:29. Fleischer compares the Arab. proverb: âlshbht âkht alkhṭyât, scepticism is the sister of sin.

Is brother - Though they take several paths, yet both come to one end.
