might know the Levites were allowed wagons to carry some of their sacred things on, Num 7:1 and a new one for the honour of the ark, as David afterwards did, Sa2 6:3 . and take two milch kine, on which there hath come no yoke; which also might be designed for the honour of the ark; but there was a further view in it, at least in the providence of God; since two such creatures, who had young, would be apt, if left to themselves, as these were, to return home to them, and not to proceed on a journey; and being unaccustomed to a yoke, would draw one way, and another another, in different ways; and not go on in a direct road, as such that are used to the yoke do: and tie the kine to the cart; in order to draw it: and bring their calves home from them; that they might not cry after them, which would cause them to turn back.
