Whether men are bound to pay tithes of all things?

Objections

Objection 1 : It would seem that men are not bound to give tithes of all things. The paying of tithes seems to be an institution of the Old Law. Now the Old Law contains no precept about personal tithes, viz. those that are payable on property acquired by one's own act, for instance by commerce or soldiering. Therefore no man is bound to pay tithes on such things.
Objection 2 : Further, it is not right to make oblations of that which is ill-gotten, as stated above (Question [86], Article [3]). Now oblations, being offered to God immediately, seem to be more closely connected with the divine worship than tithes which are offered to the ministers. Therefore neither should tithes be paid on ill-gotten goods.
Objection 3 : Further, in the last chapter of Leviticus (30,32) the precept of paying tithes refers only to "corn, fruits of trees" and animals "that pass under the shepherd's rod." But man derives a revenue from other smaller things, such as the herbs that grow in his garden and so forth. Therefore neither on these things is a man bound to pay tithes.
Objection 4 : Further, man cannot pay except what is in his power. Now a man does not always remain in possession of all his profit from land and stock, since sometimes he loses them by theft or robbery; sometimes they are transferred to another person by sale; sometimes they are due to some other person, thus taxes are due to princes, and wages due to workmen. Therefore one ought not to pay tithes on such like things.
