The Lord instructed Moses to write about that encounter and rehearse it to Joshua.
He (Joshua) was to know His intention about the Amalekites.
His battle on that day was just the beginning towards the total annihilation of the Amalekites.
There is an indication from here that God already had in mind of making Joshua the next leader of Israel.
The reading of this instruction was mainly meant for Joshua because he should be aware of the fact that he had just begun a journey unto the total conquest of the Amalekites.
As such, that writing was meant for him.
It was a prophetic matter concerning him.
Moses had to then draw his attention to this great plan that was ahead of him.
It was a one-on-one affair.
This was not a reading for the generality of Israel, but a reading specifically meant for Joshua.
It was a reading towards one of the specifics of his future ministry.
He had to hear it so that he could adhere to it.
If you don’t have anything to adhere to then you won’t have any adherent.
It is what you adhere to that determines who your adherent becomes.
You cannot remain at the ‘general level’, receiving general instructions and become great or elevated in life.
You must come to a point in life that God begins to be so particular to you before you can grow into your real intended level of accomplishment.
There are some things that every other person around you (including fellow servants of God) may be doing, but God’s specific dealing with you may not allow you to do such things because you must be different before you can make a difference.
Are you desirous and praying for an elevation in life and ministry?
Find out God’s specifics for your life and destiny.
Other people (especially other servants of God) may try to lure you into taking after their steps, but you should be careful not to miss your own prophetic specifics.
It is your understanding of these specifics that determines your goals and determination.
Moses was not reading that writing for himself, but particularly for Joshua.
There are many instructions that may come to you through the man you are under just because of you and you alone.
The benefits are not really for him, but for you.
If you obey these things you may even rise to be greater than him, because as you obey him you are already obeying God.
From this instruction, God asked Moses to move up further to the top of the mountain so that he could have an encounter that would culminate in the handing over of the Ten Commandments to him.
However, although there was no instruction permitting Joshua to go along with Moses, yet Moses decided to go with him.
How it occurred to Moses that he should go with this young man is not shown in the Scripture.
Was Moses then going with some measure of disobedience to God?
It appears that this spontaneous acceptance of Joshua into the presence of God was not acquired overnight.
Remember that Joshua was his minister.
Moses would need the services of Joshua on the mountain just as he had been doing under the mountain.
Since Joshua was useful to Moses under the mountain of encounter, he was also going to still be useful to him on the mountain.
He was going to also have some level of experience or direct encounter with the presence of God where Moses was going into.
Although the Lord may not speak to him directly the way he was to speak to Moses, but the experience of God’s presence and some specific revelations could be released to him.
Being close to a real discipler/instructor is a privilege.
On that mountain, Joshua was more privileged than the elders that were not direct servants of the great man, Moses.
His servant-hood earned him that privileged encounter.
He came face to face with the secret place of the God of his master.
His presence on that mountain did not in any way hinder the encounter that Moses had with the Lord.
He began to learn how to stay in the presence of God for a long period of time.
He was in the cloud with Moses for six days before God called Moses to come over out of the midst of the cloud to speak with him and to hand over the tables of stone upon which the Ten Commandments were written.
When you become the principal need of your God-ordained leader, you will end up as a principal need of the people under him and possibly, beyond.
Being available to such a one is tantamount to being available to God, Himself.
The dealings of God with such a man would be replicated in the life of such committed servants.
His spiritual capacity would also be replicated to his faithful and committed servants.
Thus, becoming a committed servant of a servant of God is candidature to his level or kind of encounter and authority.
It may not be the same, but there could be some level of similarity in grace at the time of your elevation.
Although Joshua was not a Levite, but an Ephraimite, his service before the great man of God who was a Levite granted him the privilege of becoming his successor.
Although he was not born into the family of the priesthood like his master, he was still going to become a leader that would be honoured like him because of his submissiveness to him.
Even the matter of the pattern of building the sanctuary which was given to Moses was done at his tarrying in the presence of God.
No wonder, he was qualified in taking over from Moses despite the fact that he was not a Levite.
It was the responsibility of Joshua to remain in the tabernacle of the congregation even while Moses leaves it to attend to some other issues outside it.
If the Lord would speak at the tabernacle in the absence of Moses, Joshua would be there to receive the message and transmit it to Moses at his return.
There is nothing wrong for a servant to receive a message that could need the attention of a leader.
True servants could have that privilege, which could even help them to pray adequately for the leader(s) and their ministry.
It could be a message of comfort, exhortation, instruction, warning.
Such a thing happened in the days of Eli when Samuel was still tender and inexperienced in the matters of the temple (1 Samuel 3:1-14).
What a privilege to be derived in being a committed and submissive servant of a genuine servant of God!
