Imamat 16:13

16:13 He must then put the incense on the fire before the Lord, and the cloud of incense will cover the atonement plate which is above the ark of the testimony, ¹  so that he will not die. ² 

Imamat 20:23

20:23 You must not walk in the statutes of the nation ³  which I am about to drive out before you, because they have done all these things and I am filled with disgust against them.

[16:13]  ¹ tn The text here has only “above the testimony,” but this is surely a shortened form of “above the ark of the testimony” (see Exod 25:22 etc.; cf. Lev 16:2). The term “testimony” in this expression refers to the ark as the container of the two stone tablets with the Ten Commandments written on them (see Exod 25:16 with Deut 10:1, 5, etc.).

[16:13]  ² tn Heb “and he will not die,” but it is clear that the purpose for the incense cloud was to protect the priest from death in the presence of the Lord (cf. vv. 1-2 above).

[20:23]  ³ tc One medieval Hebrew ms, Smr, and all the major ancient versions have the plural “nations.” Some English versions retain the singular (e.g., KJV, ASV, NASB, NRSV); others have the plural “nations” (e.g., NAB, NIV) and still others translate as “people” (e.g., TEV, NLT).
