Dealing with cattle and sheep rustlers (thieves), thieves in general, and the God-given right to self-defense against a thief/intruder (and why no man-made rules can ever change or take away these God-given rights):-
Exodus 22:1-4
22:1 If a man shall steal an ox, or a sheep, and kill it, or sell it; he shall restore five oxen for an ox, and four sheep for a sheep.
22:2 If a thief be found breaking up, and be smitten that he die, [there shall] no blood [be shed] for him.
22:3 If the sun be risen upon him, [there shall be] blood [shed] for him; [for] he should make full restitution; if he have nothing, then he shall be sold for his theft.
22:4 If the theft be certainly found in his hand alive, whether it be ox, or ass, or sheep; he shall restore double.
Deuteronomy 4:2-10
4:2 Ye shall not ADD unto the word which I command you, neither shall ye diminish [ought] from it , that ye may keep the Commandments of the "I AM" your God which I COMMAND you.
4:3 Your eyes have seen what the "I AM" did because of Baalpeor: for all the men that followed Baalpeor, the "I AM" thy God hath destroyed them [idolaters] from among you.
4:4 But ye that did cleave unto the "I AM" your God [are] alive every one of you this day.
4:5 Behold, I have taught you Statutes and Judgments, even as the "I AM" my God commanded me, that ye should do so in the land where ye go to possess it.
4:6 KEEP therefore and DO [them]; for this [is] your Wisdom and your Understanding in the sight of the nations, which shall hear all these Statutes, and say, Surely this great nation [is] a wise and understanding people.
4:7 For what nation [is there so] great, who [hath] God [so] near to them, as the "I AM" our God [is] in all [things that] we call upon Him [for]?
4:8 And what nation [is there so] great, that hath Statutes and Judgments [so] Righteous as all this Law, which I set before you this day?
4:9 Only take heed to thyself, and keep thy soul diligently, lest thou forget the things which thine eyes have seen, and lest they depart from thy heart all the days of thy life: but teach them thy sons, and thy sons' sons;
4:10 [Specially] the day that thou stoodest before the "I AM" thy God in Horeb, when the "I AM" said unto me, Gather Me the people together, and I will make them hear My Words, that they may learn to respect Me all the days that they shall live upon the earth, and [that] they may teach their children.
Deuteronomy 12:8 Ye shall not do after all [the things] that we do here this day, every man whatsoever [is] right in his own eyes .
Deuteronomy 12:32 What thing soever I command you, observe to do it: thou shalt not add thereto , nor diminish from it .
Deuteronomy 17:11-13
17:11 According to The Sentence of The Law which they shall teach thee, and according to the Judgment which they shall tell thee, thou shalt do: thou shalt not decline to do The Sentence which they shall show thee, and turn not away from it [to] the right hand, nor [to] the left.
17:12 And the man that will do presumptuously, and will not hearken unto the priest that standeth to minister there before the "I AM" thy God, or unto the judge, even that man shall die: and [thus] thou shalt put away the evil from Israel.
17:13 And all the people shall hear, and fear, and do no more presumptuously (in thinking they are a law unto themselves) .
Deuteronomy 27:26 Cursed [be] he that confirmeth not [all] the words of this Law to do them. And all the people shall say, Amen.
