'Approach' in the Bible

And they will be on Aaron and on his sons when they come to the tent of assembly or when they approach the altar to serve in the sanctuary, so that they will not bear guilt and die. [It is] a lasting statute for him and for his offspring after him.

When they come to the tent of assembly, they will wash with water so that they do not die, or when they approach the altar to serve by turning to smoke an offering made by fire to Yahweh.
