13 And Moses rose up, and his minister Joshua: and Moses went up into the mount of God.

14 And he said unto the elders, Tarry ye here for us, until we come again unto you: and, behold, Aaron and Hur are with you: if any man have any matters to do, let him come unto them.

15 And Moses went up into the mount, and a cloud covered the mount.

A number of priests and elders had stood with Moses to receive the witness of God. Now, though, when Moses went to receive the tables of stone with God’s law etched upon them, only Joshua accompanied him. It is interesting that Joshua is described here as Moses’s “minister.” The original Hebrew uses the word שָׁרַת (sharath), which is generally translated as “minister” or “servant” throughout the Bible.

Joshua would, of course, become the next leader of Israel, and so this is an interesting literal manifestation of what Jesus said when he told his disciples, “And whosoever will be chief among you, let him be your servant,” (Matthew 20:27). Joshua was literally functioning as a servant to Moses, and he really would become chief among all the Israelites.

Before Moses and Joshua ascended the mountain, Moses put the care of the congregation in the hands of Aaron and Hur. He said that any matters that needed to be addressed could be brought to those two priests. This, of course, would ultimately lead to their mischief with the golden calf in Chapter 32.
