1 sn Even though the chapter seems wearisome and repetitious to the modern reader, it is a significant document. A. Rainey shows how it matches the exact ledgers of ancient sanctuaries (see ZPEB 5:202). The recording would have been done by the priestly scribes. Of the many points that can be observed here, it should not be missed that each tribe, regardless of its size or relative importance, was on equal footing before the Lord. Each tribe shared in the work of the Lord equally. Each tribe approached the sanctuary in precisely the same way on this memorable occasion. All such devotion to the work of the Lord was to receive the blessing of God.

2 tn The idiomatic “on the day of” precedes the infinitive construct of נָכָה (nakhah) to form the temporal clause: “in the day of my striking…” becomes “when I struck.”

3 tn The construction uses the infinitive absolute and the imperfect tense of the verb “to redeem” in order to stress the point – they were to be redeemed. N. H. Snaith suggests that the verb means to get by payment what was not originally yours, whereas the other root גָאַל (ga’al) means to get back what was originally yours (Leviticus and Numbers [NCB], 268).
