John Gill's Exposition of the Whole Bible
Exodus 22:2
If a thief be found breaking up,.... An house, in order to steal money, jewels, household goods, c. or breaking through any fence, hedge, or wall of any enclosure, where oxen, or sheep, or any other creatures are, in order to take them away: the Targum of Jonathan is,
"if in the hole of a wall (or window of it) a thief be found''
that is, in the night, as appears from the following verse, "if the sun", c. to which this is opposed, as Aben Ezra observes some render it, with a digging instrument x; and it is a Jewish canon y, that
"if anyone enter with a digging instrument: he is condemned on account of his end;''
his design, which is apparent by the instrument found upon him; for, as Maimonides z observes,
"it is well known, that if anyone enters with a digging instrument, that he intends, if the master of the house opposes him to deliver his goods out of his power, that he will kill him, and therefore it is lawful to kill him; but it does not signify whether he enters with a digging instrument, either by the way of the court, or roof;''
and be smitten that he die be knocked down with a club, by the master of the house, or any of his servants, or be run through with a sword, or be struck with any other weapon, to hinder him from entrance and carrying off any of the goods of the house, and the blow be mortal: there shall no blood be shed for him: as for a man that is murdered; for to kill a man when breaking into a house, and, by all appearance, with an intention to commit murder, if resisted, in defence of a man's self, his life and property, was not to be reckoned murder, and so not punishable with death: or, "no blood" shall be "unto him" a; shall be imputed to him, the man that kills the thief shall not be chargeable with his blood, or suffer for shedding it; because his own life was risked, and it being at such a time, could call none to his assistance, nor easily discern the person, nor could know well where and whom he struck.
