Our cattle also shall go with us,.... Of every kind, of the flocks and of the herds:
there shall not an hoof be left behind; not a single creature that has an hoof: it is a proverbial expression, signifying that they should carry all that belonged to them with them:
for thereof must we take to serve the Lord our God; something of every kind and sort, all they had being devoted to his service, and to be yielded to him upon demand:
and we know not with what we must serve the Lord, until we come thither; into the wilderness; they knew not exactly and precisely what kind of creatures or how many of them, as Aben Ezra observes, they were to offer at a time; for though before this there was a known distinction between clean and unclean creatures, and the various offerings and sacrifices of the patriarchs might in a good measure direct them in the use of them; yet the special and peculiar laws about sacrifices were not given until after their deliverance, and they were got into the wilderness; so that this was not a bare pretence to get their cattle along with them, but was the true case and real matter of fact.
