They shall not be taken from it - This direction was probably given in order that the ark might not be touched by the hand (compare 2-Samuel 6:6).
The staves - shall not be taken from it - Because it should ever be considered as in readiness to be removed, God not having told them at what hour he should command them to strike their tents. If the staves were never to be taken out, how can it be said, as in Numbers 4:6, that when the camp should set forward, they should put in the staves thereof, which intimates that when they encamped, they took out the staves, which appears to be contrary to what is here said? To reconcile these two places, it has been supposed, with great show of probability, that besides the staves which passed through the rings of the ark, and by which it was carried, there were two other staves or poles in the form of a bier or handbarrow, on which the ark was laid in order to be transported in their journeyings, when it and its own staves, still in their rings, had been wrapped up in the covering of what is called badgers' skins and blue cloth. The staves of the ark itself, which might be considered as its handles simply to lift it by, were never taken out of their rings; but the staves or poles which served as a bier were taken from under it when they encamped.
The staves shall be in the rings of the ark,.... Not only be put into them, but remain in them, yea, always:
they shall not be taken from it; or, as the Septuagint version is, be immovable; so that those gold rings in the ark may signify the churches of Christ, which are instrumental to bear his name, and spread his truth in the world, comparable to rings for their circular form, being the purest and most perfect bodies of men on earth, and to gold rings for their worth and value, preciousness, excellency, and duration; and with whom the ministers of the Gospel, comparable to golden staves, are always to be, and never depart from them: or else they may signify the perfect and precious doctrines of Christ, in which his ministers are always to be; either in meditation on them, or in preaching of them, and by which they are always to abide, see 1-Timothy 4:15.
staves shall be in the rings of the ark--that is, always remain in the rings, whether the ark be at rest or in motion.
