Ben Sira 23:11

11 The one who swears many oaths is full of iniquity, and the scourge will not leave his house. If he swears in error, his sin remains on him, and if he disregards it, he sins doubly; if he swears a false oath, he will not be justified, for his house will be filled with calamities.

Ben Sira 23:11 In-Context

9 Do not accustom your mouth to oaths, nor habitually utter the name of the Holy One;

10 for as a servant who is constantly under scrutiny will not lack bruises, so also the person who always swears and utters the Name will never be cleansed from sin.

11 The one who swears many oaths is full of iniquity, and the scourge will not leave his house. If he swears in error, his sin remains on him, and if he disregards it, he sins doubly; if he swears a false oath, he will not be justified, for his house will be filled with calamities.

12 There is a manner of speaking comparable to death; may it never be found in the inheritance of Jacob! Such conduct will be far from the godly, and they will not wallow in sins.

13 Do not accustom your mouth to coarse, foul language, for it involves sinful speech.
