Bilangan 25:17

25:17 “Bring trouble ⁴  to the Midianites, and destroy them,

[4:19]  ¹ tn The word order is different in the Hebrew text: Do this…and they will live. Consequently, the verb “and they will live” is a perfect tense with a vav (ו) consecutive to express the future consequence of “doing this” for them.

[4:19]  ² tn The perfect tense with vav (ו) consecutive continues the instruction for Aaron.

[4:19]  ³ tn The distributive sense is obtained by the repetition, “a man” and “a man.”

[25:17]  ⁴ tn The form is the infinitive absolute used in place of a verb here; it clearly is meant to be an instruction for Israel. The idea is that of causing trouble, harassing, vexing Midian. The verb is repeated as the active participle in the line, and so the punishment is talionic.
