John Gill Commentary Deuteronomy 5:14

"but the seventh day is a sabbath unto Jehovah thy God: [in it] thou shalt not do any work, thou, nor thy son, nor thy daughter, nor thy man-servant, nor thy maid-servant, nor thine ox, nor thine ass, nor any of thy cattle, nor thy stranger that is within thy gates; that thy man-servant and thy maid-servant may rest as well as thou." — Deuteronomy 5:14 (ASV)

Nor your ox, nor your ass In (Exodus 20:10), it is only in general said, nor your cattle: here by way of illustration and explanation the ox and the ass are particularly mentioned; the one being used in ploughing ground, and treading out the corn, and the other in carrying burdens; and it is added, nor any of your cattle; as their camels, or whatever else they were wont to use in any kind of service; they were none of them to do any kind of work on the sabbath day. The following clause also is not used before, which expresses the end of this institution: that your manservant and your maidservant may have rest as well as you; which if the cattle had not rest, they could not have, being obliged to attend them at the plough or elsewhere; and this respects not only hired, but bond servants and maidens.
