2 tn The second line uses the image of winnowing (cf. NIV, NRSV) to state that the king’s judgment removes evil from the realm. The verb form is מִזָרֶה (mÿzareh), the Piel participle. It has been translated “to sift; to winnow; to scatter” and “to separate” – i.e., separate out evil from the land. The text is saying that a just government roots out evil (cf. NAB “dispels all evil”), but few governments have been consistently just.
3 sn The phrase with his eyes indicates that the king will closely examine or look into all the cases that come before him.
