Deuteronomy 18:15

18:15 The Lord your God will raise up for you a prophet like me from among you – from your fellow Israelites; ¹  you must listen to him.

Deuteronomy 19:19

19:19 you must do to him what he had intended to do to the accused. In this way you will purge ²  evil from among you.

Deuteronomy 21:9

21:9 In this manner you will purge out the guilt of innocent blood from among you, for you must do what is right before ³  the Lord.

¹ tc The MT expands here on the usual formula by adding “from among you” (cf. Deut 17:15; 18:18; Smr; a number of Greek texts). The expansion seems to be for the purpose of emphasis, i.e., the prophet to come must be not just from Israel but an Israelite by blood.

² tn Heb “you will burn out” (בִּעַרְתָּ, bi’arta). Like a cancer, unavenged sin would infect the whole community. It must, therefore, be excised by the purging out of its perpetrators who, presumably, remained unrepentant (cf. Deut 13:6; 17:7, 12; 21:21; 22:21-22, 24; 24:7).

³ tn Heb “in the eyes of” (so ASV, NASB, NIV).
