Leviticus 7:35

7:35 This is the allotment of Aaron and the allotment of his sons from the Lord’s gifts on the day Moses ¹  presented them to serve as priests ²  to the Lord.

Leviticus 10:9

10:9 “Do not drink wine or strong drink, you and your sons with you, when you enter into the Meeting Tent, so that you do not die, which is a perpetual statute throughout your generations, ³ 

[7:35]  ¹ tn Heb “the day he”; the referent (Moses) has been specified in the translation for clarity.

[7:35]  ² tn Heb “in the day of he presented them to serve as priests to the Lord.” The grammar here is relatively unusual. First, the verb “presented” appears to be in the perfect rather than the infinitive (but see GKC 531), the latter being normal in such temporal expressions. Second, the active verb form appears to be used as a passive plural (“they were presented”). However, if it is translated active and singular then Moses would be the subject: “on the day he [Moses] offered them [Aaron and his sons].”

[10:9]  ³ tn Heb “a perpetual statute for your generations”; NAB “a perpetual ordinance”; NRSV “a statute forever”; NLT “a permanent law.” The Hebrew grammar here suggests that the last portion of v. 9 functions as both a conclusion to v. 9 and an introduction to vv. 10-11. It is a pivot clause, as it were. Thus, it was a “perpetual statute” to not drink alcoholic beverages when ministering in the tabernacle, but it was also a “perpetual statue” to distinguish between holy and profane and unclean and clean (v. 10) as well as to teach the children of Israel all such statutes (v. 11).
