Matthew 5:33-37 ▼

33 “Again, you have heard that it was said to the men of old, ‘YOU SHALL NOT MAKE FALSE VOWS, BUT YOU SHALL FULFILL YOUR VOWS TO THE LORD [as a religious duty].’

34 But I say to you, do not make an oath at all, either by heaven, for it is the throne of God;

35 or by the earth, for it is the footstool of His feet; or by Jerusalem, for it is THE CITY OF THE GREAT KING.

36 Nor shall you make an oath by your head, for you are not able to make a single hair white or black.

37 But let your statement be, ‘Yes, yes’ or ‘No, no’ [a firm yes or no]; anything more than that comes from the evil one.
