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 Neither should you swear by your head, because you cannot make a single hair white or black.

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