'Approach' in the Bible

[Is it] too little for you that the God of Israel set you apart from the community of Israel {to allow you to approach him} to do the work of the tabernacle of Yahweh, to stand {before} the community to serve them?

{He has allowed you to approach him}, you with all your brothers, the descendants of Levi, but yet you also seek the priesthood.

[it was] a memorial for the {Israelites}, so that {no strange man} who is not from {the offspring} of Aaron should approach the presence [of] Yahweh to burn a smoke offering; he will not be like Korah and his company, just as Yahweh had spoken to him by the hand of Moses.
