"What happened to the Ark of the Covenant?"

The Bible does not record what happened to the Ark of the Covenant. Tradition says that the Prophet Jeremiah took the Ark and hid it in the catacombs beneath the temple as the Babylonians were getting ready to conquer and destroy Jerusalem. According to this tradition, the Ark remains hidden in the catacombs beneath Jerusalem, waiting for the day that a Jewish temple is rebuilt. The Babylonians conquered Jerusalem in 586 B.C. The Bible does seem to indicate that the Ark of the Covenant will be rediscovered in the end times. Revelation 11:19, "Then God's temple in heaven was opened, and within his temple was seen the ark of his covenant. And there came flashes of lightning, rumblings, peals of thunder, an earthquake and a great hailstorm."
