Tosefta, Tractate Erubin VIII
When a Jew has a Gentile in his clutches, another Jew may go to the same Gentile, lend him money and in turn deceive him, so that the Gentile shall be ruined. For the property of a Gentile, according to our law, belongs to no one, and the first Jew that passes has full right to seize it.
Schulchan Aruch, Choszen Hamiszpat 156
If it can be proven that someone has given the money of Israelites to the Goyim, a way must be found after prudent consideration to wipe him off the face of the earth.
Choschen Hamm 388, 15
Happy will be the lost of Israel, whom the Holy One, blessed be He, has chosen from amongst the Goyim, of whom the Scriptures say: "Their work is but vanity, it is an illusion at which we must laugh; they will all perish when God visits them in His wrath." At the moment when the Holy One, blessed be He, will exterminate all the Goyim of the world, Israel alone will subsist, even as it is written: "The Lord alone will appear great on that day!...
Zohar, Vayshlah 177b
That the Jewish nation is the only nation selected by God, while all the remaining ones are contemptible and hateful.
That all property of other nations belongs to the Jewish nation, which consequently is entitled to seize upon it without any scruples. An orthodox Jew is not bound to observe principles of morality towards people of other tribes. He may act contrary to morality, if profitable to himself or to Jews in general.
A Jew may rob a Goy, he may cheat him over a bill, which should not be perceived by him, otherwise the name of God would become dishonoured.
Schulchan Aruch, Choszen Hamiszpat, 348
R. Hanina said: If a heathen smites a Jew, he is worthy of death; for it is written, And he looked this way and that way, and when he saw that there was no man, he slew the Egyptian. [Ex. 2:12] R. Hanina also said: He who smites an Israelite on the jaw, is as though he had thus assaulted the Divine Presence; for it is written, one who smiteth man [i.e. an Israelite] attacketh the Holy One.
Sanhedrin 58b
[In other words, if a non-Jew kills a Jew, the non-Jew can be killed. Punching an Israelite is akin to assaulting God. (But killing a non-Jew is NOT like assaulting God.]
If a goy killed a goy or a Jew he is responsible, but if a Jew killed a goy he is not responsible.
