According to the writer of Hebrews, the tablets, the manna container, and the staff all ended up within the Ark. (Hebr. 9:4). However, as you noted, only the stone tablets were reported as being inside the Ark when Solomon took it into the Temple (see 1 Kings 8:9). Perhaps they were placed inside with the other holy objects by King David after they were recovered from the rubble following the destruction of the temple by Nebuchadnezzar.
We don't know where or how the tablets were preserved after that, but we do know that Moses continued to receive them through the hands of Joshua (see Josh 23:1-8).
The manna that fell each day for the Israelites was probably collected before it dried out and stored in containers made of clay or wood. The Israelites then ate their meal during the night when the manna was still fresh. When they entered Canaan at the end of the forty years in the wilderness, they brought some of this manna with them to serve as a reminder of how God provided for them during their time of need.
I hope this has been helpful in understanding what may have happened to the tablets and manna container after they were taken out of the temple following its destruction by Babylonians in 586 B.C..
When the Babylonians demolished the temple, they were most likely just dumped. Remember that the ark of the covenant, like many other items in Solomon's temple, was plated with gold. This would have made it very valuable, which may be why the Babylonians didn't destroy it.
Instead, they took the gold off the ark and used it for their own purposes. Today, this gold is kept in the Iraq National Museum in Baghdad. It's a pretty amazing sight!
After the exile, people believed that God would never allow another human being to suffer the same fate as He had allowed His chosen people. So, they stopped making sacrifices and told stories about how the manna had given them enough food for life. However, God never said that manna was necessary for survival. He only required certain sacrifices to be offered regularly at the temple in Jerusalem.
Since there was no longer a temple, the people began to worship God anywhere they could find Him. Some people continued to offer sacrifices but others didn't.
It wasn't until about 600 B.C. that King Josiah started a religious revival in Judah. People began to read the law of Moses again for the first time in hundreds of years.
The two tablets engraved with the Ten Commandments The book of Exodus (31:18; 32:15-16) describes Moses receiving from God the "tablets of the testament" written with "God's finger." Christians believe that these are the same tablets on which Moses saw the ten commandments, but they also believe that Jesus is the son of God and thus could not have been lying when he said that he would one day die for our sins. They also believe that the Holy Spirit will continue to guide Christians through dreams, voices, and other means after Jesus' death and before his return.
According to Christian tradition, shortly before he died Jesus told his disciples that he would rise from the dead on the third day and then ascended into heaven.
At his ascension, Jesus left the apostles behind him to lead the church. During their time of leadership, the apostles wrote many books about Jesus' life and teachings. These books are known as the New Testament.
Christianity is the largest religion in the world with over 1.6 billion followers or 18% of the global population. It is growing rapidly in Asia and Africa.
Christianity has produced many influential people in history, such as Saint Paul, Thomas Edison, and Bill Clinton.
