Numbers 27:12
12 Then the Lord said to Moses, “Go up this mountain of the Abarim range, and see the land I have given to the Israelites. 13 When you have seen it, you will be gathered to your ancestors, as Aaron your brother was gathered to his ancestors. 14 For in the wilderness of Zin when the community rebelled against me, you rebelled against my command to show me as holy before their eyes over the water—the water of Meribah in Kadesh in the wilderness of Zin.”
LXX Numbers 27:12
12 And the Lord said to Moses, Go up to the mountain that is in the country beyond Jordan, this mount Nabau, and behold the land Chanaan, which I give to the sons of Israel for a possession. 13 And thou shalt see it, and thou also shalt be added to thy people, as Aaron thy brother was added to them in mount Or: 14 because ye transgressed my commandment in the wilderness of Sin, when the congregation resisted and refused to sanctify me; ye sanctified me not at the water before them. This is the water of Strife in Cades in the wilderness of Sin.

"... Numbers 27:12 ... The Greek version adds “which is Mount Nebo.” This is a typical scribal change to harmonize two passages. The area is in the mountains of Moab; Deuteronomy 34:1 more precisely identifies it as Mount Nebo ..."

"... Intertextual harmonizations ... Sometimes new connections appear ... The tale of the call of Joshua in Numbers 27 includes in verse 12 the command, “Go up this mountain of the Abarim range, and see the land that I have given to the Israelites.” Yet Numbers 27:12 LXX reads as follows: “Go up into the mountain that is on the other side (of this Mount Nabau), and see the land Chanaan, which I am giving to the sons of Israel for a possession.” The plusses Χανααν and ἐν κατασχέσει enhance a connection to God’s promise in Genesis 17:8. The same term is applied to both the worm that attacked Jonah’s plant (Jonah 4:7) and the worm that made the manna go bad (Exodus 16:20). The graphical similarity between עלות and תעלות suggests that a correction had already arisen in a Hebrew milieu ..."
