Moses said: "Our livestock also must go with us; not a hoof shall be left behind, for we must take of them to serve the LORD our God, and we do not know with what we must serve the LORD until we arrive there."
Moses gives a very good reason why they must take their cattle with them; they must go to do sacrifice, and therefore they must take wherewithal. What numbers and kinds of sacrifices would be required they did not yet know, and therefore they must take all they had.
Note, With ourselves, and our children, we must devote all our worldly possessions to the service of God, because we know not what use God will make of what we have, nor in what way we may be called upon to honour God with it.
