29. In fact, any humans who have been promised to me in this way must be put to death.
30. Ten per cent of everything you harvest is holy and belongs to me, whether it grows in your fields or on your fruit trees.
31. If you want to buy back this part of your harvest, you may do so by paying what it is worth plus an additional twenty per cent.
32. When you count your flocks and herds, one out of ten of every newborn animal is holy and belongs to me,
33. no matter how good or bad it is. If you substitute one animal for another, both of them become holy, and neither can be bought back.
