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 22:29

22:29 “Do not hold back offerings from your granaries or your vats. ⁴  You must give me the firstborn of your sons.

[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.”

[22:29]  ⁴ tn The expressions are unusual. U. Cassuto renders them: “from the fullness of your harvest and from the outflow of your presses” (Exodus, 294). He adds the Hittite parallel material to show that the people were to bring the offerings on time and not let them overlap, because the firstfruits had to be eaten first by the priest.
