Keluaran 13:2

13:2 “Set apart ¹  to me every firstborn male – the first offspring of every womb ²  among the Israelites, whether human or animal; it is mine.” ³ 

Keluaran 29:24

29:24 You are to put all these ⁴  in Aaron’s hands ⁵  and in his sons’ hands, and you are to wave them as a wave offering ⁶  before the Lord.

[13:2]  ¹ tn The verb “sanctify” is the Piel imperative of קָדַשׁ (qadash). In the Qal stem it means “be holy, be set apart, be distinct,” and in this stem “sanctify, set apart.”

[13:2]  sn Here is the central principle of the chapter – the firstborn were sacred to God and must be “set apart” (the meaning of the verb “sanctify”) for his use.

[13:2]  ² tn The word פֶּטֶּר (petter) means “that which opens”; this construction literally says, “that which opens every womb,” which means “the first offspring of every womb.” Verses 12 and 15 further indicate male offspring.

[13:2]  ³ tn Heb “to me it.” The preposition here expresses possession; the construction is simply “it [is, belongs] to me.”

[29:24]  ⁴ tn Heb “the whole” or “the all.”

[29:24]  ⁵ tn Heb “palms.”

[29:24]  ⁶ tn The “wave offering” is תְּנוּפָה (tÿnufah); it is, of course, cognate with the verb, but an adverbial accusative rather than the direct object. In Lev 23 this seems to be a sacrificial gesture of things that are for the priests – but they present them first to Yahweh and then receive them back from him. So the waving is not side to side, but forward to Yahweh and then back to the priest. Here it is just an induction into that routine, since this is the ordination of the priests and the gifts are not yet theirs. So this will all be burned on the altar.
