Leviticus 10:9
8 Then the Lord spoke to Aaron, 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. This is a perpetual statute throughout your generations, 10 as well as to distinguish between the holy and the common, and between the unclean and the clean,
LXX Leviticus 10:9
8 And then the Lord spoke to Aaron, saying, 9 “Do not drink wine and strong drink, you and your sons with you, when you enter into the tent of testimony or when you advance toward the altar, and you will certainly not die. This is a perpetual law throughout your generations: 10 to discern between the holy and unholy, and between the unclean and clean
Notes and References
"... we record cases in which scribes adapted elements in the text to other details appearing either in the same verse or in the immediate or remote context. The decision regarding whether or not a certain detail reflects a harmonization to another verse is always subjective since it is never certain that this thought process indeed took place. Likewise, it is equally subjective to decide that the LXX and SP agree against MT because sometimes secondary developments took place independently in both sources, such as the change from singular to plural or vice versa ... by definition, all harmonizing additions represent secondary developments. They were made in order to adapt one context to another one. /However, the fullness of the wording is often artificial and, in some cases, the additions are clearly secondary, a feature that is more recognizable in Genesis and Deuteronomy than in Leviticus ... This verse in the Septuagint of Leviticus 10:9 exemplifies the expertise of the scribe/editor who remembered the parallel verse in Exodus in which the approaching of the Tent of Meeting was mentioned together with the nearing of the altar with similar implications of danger ..."
