Leviticus 24:3
2 “Command the Israelites to bring to you pure oil of beaten olives for the light, to make a lamp burn continually. 3 Outside the special curtain of the congregation in the Meeting Tent, Aaron must arrange it from evening until morning before the Lord continually. This is a perpetual statute throughout your generations. 4 On the ceremonially pure lampstand he must arrange the lamps before the Lord continually.
LXX Leviticus 24:3
2 “Charge the sons of Israel, and let them receive pure olive oil for me, beaten out for a light source, to light a lamp perpetually. 3 Aaron and his sons will keep burning it outside of the veil in the tent of testimony from evening until early morning, in the presence of the Lord continuously; this is a perpetual law throughout your generations. 4 On the pure lampstand you will kindle the lamps before the Lord until morning.
Notes and References
"... Apart from the errors that occurred during the transmission history of the text of Leviticus, literary considerations may explain some textual discrepancies. Indeed, there are cases in Leviticus where different readings allow different interpretations, so that one cannot easily assert that they are mistaken readings. Such interpretations can be observed for instance in Leviticus 9 and 24. It seems that the tasks of the high priest and those of the ordinary priests have been adjusted in some witnesses ... A reversed case occurs in Leviticus 24:3-4. Here the Masoretic text asserts that Aaron (the high priest) alone is in charge of preparing and kindling the lamps of the Menorah. However, according to the Samaritan Pentateuch and Septuagint, this task is attributed to “Aaron and his sons,” which means all of the priests. It is possible that their reading resulted from harmonization with Exodus 27:20-21, where “Aaron and his sons” is read in all the witnesses ... Interestingly, 11QTa IX,13-14 asserts that the lamps are arranged by the priests, sons of Aaron, while Aaron himself is not mentioned for this task. Thus, there is like a literary evolution and discussion dealing with who is in charge of the lamps of the Menorah ..."
