Interestingly the Ark contains two elements that make it perfect or complete. One that seen and other that not seen.
Sort of like the unseen mutual work of the faith of the father and Son of man, Jesus working as a labor of their love Like in Isiah 53 two working together to bring us the peace of God that surpasses our understandings. One seen the other not seen
Jesus as that seen relying on the unseen father described as the spiritual food needed to perform the spiritual work. The kind of food of doing the will of another that the disciples knew not of at first.
Jesus therefore answered and said unto them, Murmur not among yourselves. No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.It is written in the prophets, And they shall be all taught of God. Every man therefore that hath heard, and hath learned of the Father, (unseen) cometh unto me ( Seen).John 6:43-45
Or I and the father are one
Two sides.or elements make up the Ark ..……... inside not seen, and outside seen, or two witnesses to one perfect work. We can see that work using Moses and Aaron one to represent walking faith the unseen the other walking by sigh as that see,
Exodus 4:13-16 King James Version (KJV)And he said, O my Lord, send, I pray thee, by the hand of him whom thou wilt send. And the anger of the Lord was kindled against Moses, and he said, Is not Aaron the Levite thy brother? I know that he can speak well. And also, behold, he cometh forth to meet thee: and when he seeth thee, he will be glad in his heart.And thou shalt speak unto him, and put words in his mouth: and I will be with thy mouth, and with his mouth, and will teach you what ye shall do.And he shall be thy spokesman unto the people: and he shall be, even he shall be to thee instead of a mouth, and thou shalt be to him instead of God.
There again as a picture of the Ark two witnesses working as one, that seen and, that unseen.
As Moses seen represent the letter of the law that kills. Aaron not seen a faith issue as a member of the priesthood of believers Those hold out the gospel in what is considered a foreign land as ambassadors for Christ not of here..
God knowing them beforehand of the rebellion which will break out when Moses died as a sign of rebellion against them that challenged the law of God by the letter . The Holy Spirit had Moses place the written book of the law on the side of the Ark as a warning to what is the inside the hidden witness . The two tablets having destroyed the ones hewn by the finger of God. God perving the written tradition as the only , commanded Moses to hewn out two more stones which again were written by the finger of God as his witness . another hidden witness the witness of Aaron's the staff that showed those who rebel against the word of God and the third mana , you could say hidden as to the unseen spiritual understanding like that in Revelation 2:7
Deuteronomy 31:25-27 King James Version (KJV)That Moses commanded the Levites, which bare the ark of the covenant of the Lord, saying,Take this book of the law, and put it in the side of the ark of the covenant of the Lord your God, that it may be there for a witness against thee.For I know thy rebellion, and thy stiff neck: behold, while I am yet alive with you this day, ye have been rebellious against the Lord; and how much more after my death?
