20 Only, the tree, which thou knowest that it [is] not a fruit-tree, it thou dost destroy, and hast cut down, and hast built a bulwark against the city which is making with thee war till thou hast subdued it.
20
However, you may cut down trees that you know are not fruit trees and use them to build siege works until the city at war with you falls.
