There are verbs which deal with what a man is commanded to do, even that which he does not do himself. And this applies to all of the work for which the way to do it is through laborers, like building houses, working in the fields, digging holes, etc. And when mentioning these verbs in general business, like general planting (to exclude planting one tree, etc.), it will also be done by means of other people.

And moreover, the verb עשה applies whether he does it himself or it is done through his orders. And there is a difference in this between whether it says in singular לא תעשה לך or it says in plural לא תעשו לכם; when in plural, those who participate in an action will only be by means of other people.
