Matthew 5:34-37 ▼

34 But I tell you, don’t take an oath at all: either by heaven, because it is God’s throne;

35 or by the earth, because it is his footstool; or by Jerusalem, because it is the city of the great King.

36 Do not swear by your head, because you cannot make a single hair white or black.

37 But let your ‘yes’ mean ‘yes,’ and your ‘no’ mean ‘no.’ Anything more than this is from the evil one.
