¹⁹ When you lay siege to a city for a long time, fighting against it to capture it, do not destroy its trees by putting an ax to them, because you can eat their fruit. Do not cut them down. Are the trees people, that you should besiege them?^{[a] 20} However, you may cut down trees that you know are not fruit trees^(A) and use them to build siege works until the city at war with you falls.

A Tree and Its Fruit^(A)

⁴³ “No good tree bears bad fruit, nor does a bad tree bear good fruit. ⁴⁴ Each tree is recognized by its own fruit.^(B) People do not pick figs from thornbushes, or grapes from briers. ⁴⁵ A good man brings good things out of the good stored up in his heart, and an evil man brings evil things out of the evil stored up in his heart. For the mouth speaks what the heart is full of.^(C)
