Sirach 23:12LXX

10And let not the naming of God be usual in thy mouth, and meddle not with the names of saints, for thou shalt not escape free from them.

11For as a slave daily put to the question, is never without a blue mark: so every one that sweareth, and nameth, shall not be wholly pure from sin.

12A man that sweareth much, shall be filled with iniquity, and a scourge shall not depart from his house.

13And if he make it void, his sin shall be upon him: and if he dissemble it, he offendeth double:

14And if he swear in vain, he shall not be justified: for his house shall be filled with his punishment.
