Solomon
Proverbs 4:15ESV·traditional attribution

Avoid it; do not go on it; turn away from it and pass on.

Matthew Henry Presbyterian @wholebiblehenry

Some make David's instructions to Solomon, which began Pro 4:4, to continue to the end of the chapter; nay, some continue them to the end of the ninth chapter; but it is more probable that Solomon begins here again, if not sooner. In these verses, having exhorted us to walk in the paths of wisdom, he cautions us against the path of the wicked. 1.

Avoid it,.... As dangerous and pernicious, as abominable and detestable; or, "flee from it", as the Vulgate Latin version: Jarchi and Gersom interpret it, "make it void"; cause it to cease, destroy it, do all you can to hinder the wicked from accomplishing their designs; pass not by it; do not come near it; keep at a distance from it, that you may not be...

Pro 4:15 On פּרעהוּ, avoid it (the way), (opp. אחז, Job 17:9; תּמך, Psa 17:5), see under Pro 1:25. שׂטה, elsewhere (as the Arab. shatt, to be without measure, insolent) used in malam partem, has here its fundamental meaning, to go aside. מעליו (expressed in French by de dessus, in Ital. by di sopra) denotes: so that thou comest not to stand on it.
