Exodus 22:6

“If fire break out, etc.] Even though of itself, as Jarchi interprets it: and catch in thorns a thorn hedge or fence, with which cornfields might be en closed: so that the stacks of corn, or the standing corn, or the field, be consumed [therewith]; whether it be corn cut down, bound up in sheaves, and laid up in heaps or stacks, or whether it be yet growing, and not fully ripe, at least not cut down, or any other fruits of the field; if the fire that takes the thorns which are near them should reach to those, and kindle upon them and destroy them: he that kindleth the fire, shall surely make restitution: that is, though he kindles the fire upon his own ground, yet being careless of it, it…”

“If fire break out, and catch in thorns--This refers to the common practice in the East of setting fire to the dry grass before the fall of the autumnal rains, which prevents the ravages of vermin, and is considered a good preparation of the ground for the next crop. The very parched state of the herbage and the long droughts of summer, make the kindling of a fire an operation often dangerous, and always requiring caution from its liability to spread rapidly. stacks--or as it is rendered "shocks" (Jdg 15:5; Job 5:26), means simply a bundle of loose sheaves.”

“He that designed only the burning of thorns might become accessary to the burning of corn, and should not be held guiltless. If the fire did mischief, he that kindled it must answer for it, though it could not be proved that he designed the mischief. Men must suffer for their carelessness, as well as for their malice. It will make us very careful of ourselves, if we consider that we are accountable not only for the hurt we do, but for the hurt we occasion through inadvertency. Exodus 22:7”

“If fire break out: Mr. Harmer observes, that it is a common custom in the East to set the dry herbage on fire; which fires, from want of care, often produce great damage. Hence a law to guard against such evils was highly expedient. so that the stacks of corn: Jdg 15:4, Jdg 15:5; Sa2 14:30, Sa2 14:31 he that kindled the fire: Exo 22:9, Exo 22:12, Exo 21:33, Exo 21:34 Exodus 22:7”
