In Judaism, "chosenness" is the belief that the Jews, via descent from the ancient Israelites, are the chosen people, i.e. chosen to be in a covenant with God. The idea of the Israelites being chosen by God is found most directly in the Book of Deuteronomy as the verb bahar (בָּחַ֣ר (Hebrew)), and is alluded to elsewhere in the Hebrew Bible using other terms such as "holy people". Much is written about these topics in rabbinic literature. The three largest Jewish denominations— Orthodox Judaism, Conservative Judaism and Reform Judaism—maintain the belief that the Jews have been chosen by God for a purpose. Sometimes this choice is seen as charging the Jewish people with a specific mission — to be a light unto the nations, and to exemplify the covenant with God as described in the Torah.
This view, however, did not preclude a belief that God has a relationship with other peoples — rather, Judaism held that God had entered into a covenant with all humankind, and that Jews and non-Jews alike have a relationship with God. Biblical references as well as rabbinic literature support this view: Moses refers to the "God of the spirits of all flesh" (Numbers 27:16), and the Tanakh (Hebrew Bible) also identifies prophets outside the community of Israel. Based on these statements, some rabbis theorized that, in the words of Nethanel ibn Fayyumi, a Yemenite Jewish theologian of the 12th century, "God permitted to every people something he forbade to others...[and] God sends a prophet to every people according to their own language."(Levine, 1907/1966) The Mishnah states that "Humanity was produced from one man, Adam, to show God's greatness. When a man mints a coin in a press, each coin is identical. But when the King of Kings, the Holy One, blessed be He, creates people in the form of Adam not one is similar to any other." (Mishnah Sanhedrin 4:5) The Mishnah continues, and states that anyone who kills or saves a single human, not Jewish, life, has done the same (save or kill) to an entire world. The Tosefta, an important supplement to the Mishnah, also states: "Righteous people of all nations have a share in the world to come" (Sanhedrin 105a).
