Thematic Bible: Israel being separate from all other people

" 'And you shall keep all my statutes and all my regulations, and you shall do them, so that the land, to which I am bringing you to inhabit it, shall not vomit you out. And you shall not follow the statutes of the nation that I am driving out {from before you}, because they did all these things, and I detested them. So I said to you, "You yourselves shall take possession of their land, and I myself shall give it to you to possess it--a land flowing with milk and honey"; I [am] Yahweh your God, who {has set you apart} from the nations. read more.
And you shall distinguish between the clean and the unclean animal and between the unclean and the clean bird; and you shall not defile yourselves with the animal or with the bird or with anything that moves along the ground that I have set apart for you {as unclean}. And you shall be holy for me, because I, Yahweh, [am] holy, and I have singled you out from the nations to be mine.

for they [are] your people and your inheritance whom you brought from Egypt from the middle of the smelter of iron. [O,] that your eyes [may] be open to the plea of your servant and to the plea of your people Israel, to listen to them in all things [when] they call to you. For you have separated them for yourself as an inheritance from all the peoples of the earth, as you promised through the hand of Moses your servant when you brought out our ancestors from Egypt, my Lord Yahweh!"
