Ark of the Covenant-Most Holy Place

And after the second veil, the tabernacle which is called the Holiest of all; Hebrews 9:3 Only the High priest could enter the Most Holy place once a year on the Day of Atonement (Yom Kippur). And the LORD said unto Moses, Speak unto Aaron thy brother, that he come not at all times into the holy place within the vail before the mercy seat, which is upon the ark; that he die not: for I will appear in the cloud upon the mercy seat. And he shall take of the blood of the bullock, and sprinkle it with his finger upon the mercy seat eastward; and before the mercy seat shall he sprinkle of the blood with his finger seven times. Leviticus 16:2,14

The Ark of the Covenant contained the 10 Commandment stone tablets ...and put the tables in the ark which I had made; and there they be, as the LORD commanded me. Deuteronomy 10:5 (The Law which He would one day come down and show them how to live- Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. Matthew 5:17).

It also contained a jar of manna (the food which God fed them with in the desert) and Aaron's rod which had blossomed with leaves. Which had the golden censer, and the ark of the covenant overlaid round about with gold, wherein was the golden pot that had manna, and Aaron's rod that budded, and the tables of the covenant; Hebrews 9:4 *** The MANNA from heaven-They said therefore unto him, What sign shewest thou then, that we may see, and believe thee? what dost thou work? Our fathers did eat manna in the desert; as it is written, He gave them bread from heaven to eat. Then Jesus said unto them, Verily, verily, I say unto you, Moses gave you not that bread from heaven; but my Father giveth you the true bread from heaven. For the bread of God is he which cometh down from heaven, and giveth life unto the world. Then said they unto him, Lord, evermore give us this bread. And Jesus said unto them, I am the bread of life: John 6:30-35 *** Aaron's rod, of the first High Priest- Wherefore, holy brethren, partakers of the heavenly calling, consider the Apostle and High Priest of our profession, Christ Jesus; Hebrews 3:1 Feed thy people with thy rod, the flock of thine heritage... Micah 7:14
Above the ark was the Mercy Seat of God. Notice His "MERCY SEAT" is over His Law inside the ark-for what is sin? ....for sin is the transgression of the law. 1 John 3:4 And thou shalt put the mercy seat upon the ark of the testimony in the most holy place. Exodus 26:34
And he said unto me, Unto two thousand and three hundred days; then shall the sanctuary be cleansed. Daniel 8:14 (2,300 years)
