Contradiction with 2 Chronicles 5:9
This verse states that the staves of the ark were visible from the holy place, which may imply they were sometimes moved, unlike the permanent placement suggested in Exodus 25:15.
2 Chronicles 5:9: And they drew out the staves [of the ark], that the ends of the staves were seen from the ark before the oracle; but they were not seen without. And there it is unto this day. [there...: or, they are there]
Contradiction with Numbers 4:6
This verse instructs the staves to be put in when the tabernacle moves, suggesting they were not meant to always remain in place as Exodus 25:15 suggests.
Numbers 4:6: And shall put thereon the covering of badgers' skins, and shall spread over [it] a cloth wholly of blue, and shall put in the staves thereof.
Contradiction with 1 Kings 8:8
This verse mentions that the staves were drawn out, again indicating movement, which contradicts the idea that they should always remain without being moved.
1 Kings 8:8: And they drew out the staves, that the ends of the staves were seen out in the holy [place] before the oracle, and they were not seen without: and there they are unto this day. [ends: Heb. heads] [holy...: or, ark]
