Deuteronomy 13:9

13:9 Instead, you must kill him without fail! ¹  Your own hand must be the first to strike him, ²  and then the hands of the whole community.

¹ tn The Hebrew text uses the infinitive absolute for emphasis, which the translation indicates with the words “without fail” (cf. NIV “you must certainly put him to death”).

² tn Heb “to put him to death,” but this is misleading in English for such an action would leave nothing for the others to do.
