Numbers 23:19

Or has he spoken, and will he not make it happen? 6
1 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).
2 tn The expression for “in the open field” is literally “upon the face of the field” (עַל־פְּנֵי הַשָּׂדֶה, ’al pÿne hassadeh). This ruling is in contrast now to what was contacted in the tent.
3 tn Heb “a dead body”; but in contrast to the person killed with a sword, this must refer to someone who died of natural causes.
4 sn See Matt 23:27 and Acts 23:3 for application of this by the time of Jesus.
5 tn Heb “son of man.”
6 tn The verb is the Hiphil of קוּם (qum, “to cause to rise; to make stand”). The meaning here is more of the sense of fulfilling the promises made.
