Talmud zu Wajikra 26:34

Exile comes into the world because of idolatry, sexual transgression, murder, and not letting the land rest during the sabbatical year. Idolatry, as it says (Leviticus 26:30), “I will destroy your altars.” The Holy Blessed One said: Since you want to worship idols, I will exile you to a place where they worship idols. That is why it says, “I will destroy your altars.” Not letting the land rest during the sabbatical year, as it says (Leviticus 26:34), “Then shall the land make up for its sabbatical years [throughout all the time that it is desolate and you are in the land of your enemies].” The Holy Blessed One said to them: Since you do not let the land rest, it will rest by itself, and the number of months that you did not let it rest, it will rest by itself. That is why it says, “Then shall the land make up…all the time.” (Sexual transgression: How so? Rabbi Yishmael son of Rabbi Yosei said: As long as Israel commits sexual transgressions, the Divine Presence removes Itself from them, as it says (Deuteronomy 23:15), “Let no unseemly [lit., naked] thing be seen among you, so that [God] will turn away from you.”)
