When did the Ark of the Covenant disappear from view?
The supplied teaching does not determine when the Ark of the Covenant disappeared from view. It states the Ark was present at the time of the Babylonian invasion, but the teacher could find no record that Nebuchadnezzar or the Babylonians carried it away. He therefore leaves the question open for further Bible study.
Les raises the disappearance of the Ark of the Covenant as an open question he cannot answer from the record. He notes that the Ark was still there at the time of the Babylonian invasion, but he cannot find anything showing that the Babylonians under Nebuchadnezzar took the Ark with them. Earlier he also asks when the Ark stopped containing Aaron's rod that budded and the sample of manna and had only the tables of stone. He leaves these as questions for Bible study and invites anyone with a hint to share it.
