Deuteronomy 5:14

Nor thine ox, nor thine ass
In ( Exodus 20:10 ) , it is only in general said,

nor thy 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 thy 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 thy manservant and thy maidservant may have rest as well as
thee;
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.
