33 “Again you have heard that it was said to those of old, ‘You shall not swear falsely, but shall perform your oaths to the Lord.’ 34 But I say to you, do not swear at all: neither by heaven, for it is God’s throne; 35 nor by the earth, for it is His footstool; nor by Jerusalem, for it is the city of the great King. 36 Nor shall you swear by your head, because you cannot make one hair white or black. 37 But let your ‘Yes’ be ‘Yes,’ and your ‘No,’ ‘No.’ For whatever is more than these is from the evil one (Matthew 5:33–37, NKJV).”
Citizens of the kingdom of heaven are people of integrity. They keep their word. The Jews had invented ingenious ways to circumvent honesty while still claiming to be honest. They thought they could swear by the temple and free themselves from their pledge. But, they said an oath made by the temple’s gold obliged one to keep it (Matt. 23:16). Jesus said they were blind fools for making such false oaths (Matt. 26:17, 18-22). It is intriguing and pertinent that today’s passage (that emphasizes the integrity of keeping one’s word) immediately follows Christ’s declaration of the sanctity of marriage (Matt. 5:31-32). The marriage vow is for life (“until death we do part”), and yet too many break their vow and think they are freed from their obligation made to and before God (Matt. 19:6; Rom. 7:2-3). The Christian’s word is trustworthy and dependable in all matters. Playing word games to evade the truth and our moral responsibility makes us no different from the scribes and Pharisees (Matt. 5:20). Let your word be your bond. People notice, and so does the Lord (Matt. 5:13-16; 1 Pet. 2:12; Ps. 15:4).
