Exodus 22

6. 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" ( Judges 15:5 , Job 5:26 ), means simply a bundle of loose sheaves.

26, 27. If thou at all take thy neighbour's raiment to pledge, &c.--From the nature of the case, this is the description of a poor man. No Orientals undress, but, merely throwing off their turbans and some of their heavy outer garments, they sleep in the clothes which they wear during the day. The bed of the poor is usually nothing else than a mat; and, in winter, they cover themselves with a cloak--a practice which forms the ground or reason of the humane and merciful law respecting the pawned coat.

28. gods--a word which is several times in this chapter rendered "judges" or magistrates.
the ruler of thy people--and the chief magistrate who was also the high priest, at least in the time of Paul ( Acts 23:1-5 ).
