33 [ref]“Also you’ve heard that it was said to our ancestors that you shouldn’t break your oath, but you must do whatever you promised to the master. 34 [ref]But I’m telling you not to make oaths in the first place—don’t swear by heaven because it’s God’s throne, 35 [ref]nor by the earth because it’s God’s footrest, nor by Jerusalem because it’s the supreme king’s city. 36 And don’t swear by your own strength because you can’t even make one strand of hair grow a different colour. 37 Just say ‘yes’ when you commit to doing something, and ‘no’ when you don’t, because going beyond that is actually evil.
