“And they departed from the mount of the LORD three days' journey: and the ark of the covenant of the LORD went before them in the three days' journey, to search out a resting place for them.”
King James Version (KJV)
10:33 Three days - With continued journeys; only it seems probable, that the cloud made little pauses that they might have time for sleep and necessary refreshments. The ark went before them - Altho' in their stations it was in the middle, yet in their marches it went before them; and the cloud was constantly over the ark whether it stood or went; therefore the ark is said to go before and direct them, not as if the ark could be seen of all the camps, which being carried only upon mens shoulders was impossible; but because the cloud, which always attended upon the ark, and did, together with the ark, constitute, in a manner, one sign of God's presence, did lead and direct them. To search out - A metaphorical expression, for discovering to them; for the ark could not search, and God, who knew all places and things, needed not to search.
