How is an admonition administered to the person taking the oath? We tell him: Know that the entire world trembled at the time the Holy One, blessed be He, told Moses [Exodus 20:7]: "Do not take the name of God, your Lord, in vain." For with regard to all the transgressions in the Torah, as [Exodus 34:7] states: "And He shall cleanse." And with regard to [a false oath,] as [Exodus 20:7] states: "[God] will not cleanse one who takes His name in vain."
With regard to all the transgressions in the Torah, retribution is exacted from him [alone], but with regard to [a false oath], retribution is exacted from him and from his family who conceal the matter for him. Moreover, this causes retribution to be exacted from "the enemies of the Jews," for the entire Jewish people are responsible for each other, for [Hoshea 4:2-3] states: "Swearing, denying, murdering.... Therefore the land will mourn and all who inhabit it will be forlorn."
With regard to all the transgressions in the Torah, [retribution] is suspended for two or three generations if he possesses merit, but with regard to [a false oath], retribution is exacted immediately, as [Zechariah 5:4] states: 'I have let loose [the curse],' declares God, the Lord of Hosts, 'It will come into the house of the thief and the house of he who took an oath in My name falsely.'
"I have let loose" implies immediately. "It will come into the house of the thief" - this refers to deceiving people, i.e. one who does not have money owed to him by a colleague and yet lodges a claim against him to require him to take an oath. "He who took an oath in My name falsely" - this should be interpreted literally. [The verse continues:] "It shall destroy it, its wood, and its stones." Entities that cannot be destroyed by fire and water will be destroyed by a false oath.
