Fret not thyself because of evildoers,.... The saints may be grieved at them and for them, because of their evil doings, and may be angry with them for them; yet are not to show any undue warmth, at least in an indecent way, by calling them opprobrious names; for the words may be rendered, "do not show thyself warm" or "angry" (i): in a sinful way; or fret not at their outward prosperity, as it is explained Psa 37:7. The Targum adds, "to be like them", which agrees with Psa 37:8; neither be thou envious against the workers of iniquity; that is, at their present temporal happiness; see Psa 73:3. The Targum adds, as before, to be joined with them; which sense some parallel places seem to incline to, Pro 3:31. (i) "ne accendaris ira", Junius & Tremellius; "ne exardescas", Gejerus, Michaelis.
