21 You then, the one habitually teaching another (a different one), are not habitually teaching yourself! You, the one constantly preaching (proclaiming; heralding), “Do not steal,” are habitually stealing!
22 The person continually saying not to be committing adultery, you are habitually committing adultery! You, the one repeatedly detesting idols (responding to forms, shapes or concepts as an abomination, as something that is foul and stinks), are in the habit of robbing temples (despoiling or profaning the sanctuary)! [note: vss. 21-22 can also be rendered as questions]
23 You who are boasting in law (or: [the] Law [= Torah]; or: a law), through the transgression of (stepping across the line of; stepping to the side of; deviating from) the Law, you are constantly dishonoring (devaluing) God,
24 for according as it has been, and stands, written [in the Tanakh (Hebrew Scriptures)], "Because of you, God’s NAME [Yahweh?] is continuously being blasphemed (vilified; misrepresented; slandered; given a false image which hinders the Light) among the ethnic multitudes (nations; non-Jews; Gentiles)." [Isa. 52:5; Ezk. 36:20]
