'Approach' in the Bible

Moses alone is to approach the Lord, but the others are not to approach, and the people are not to go up with him.”

These must be worn by Aaron and his sons whenever they enter the tent of meeting or approach the altar to minister in the sanctuary area, so that they do not incur guilt and die. This is to be a permanent statute for Aaron and for his future descendants.

Whenever they enter the tent of meeting or approach the altar to minister by burning up an offering to the Lord, they must wash with water so that they will not die.
