And do not take an oath by your head, for you cannot make one hair white or black.
English Standard Version (ESV)
Swearing by your head highlights a subtle but crucial point: you have absolutely no control over even the smallest details of your own being, like the color of a single hair. This isn't just about avoiding empty words; it's a reminder that our very existence and its maintenance are entirely in God's hands.
And do not take an oath by your head, for you cannot make one hair white or black.
English Standard Version (ESV)
Jesus is contrasting his teachings with the common interpretations and practices of the Pharisees, who focused on the letter of the law rather than its spirit. He has already addressed anger and lust, now he moves to oaths, showing how superficial compliance misses the deeper call to truthfulness and integrity. He's revealing that even seemingly harmless oaths, like swearing by one's own head, violate God's intention by using something that ultimately belongs to God's authority.
Why would Jesus tell us not to swear by our own heads? It seems like our own property, right? But Jesus reveals a deeper truth about who's really in control.
Jesus tackles the common practice of swearing by one's head. This wasn't just a casual phrase; it was a way to pledge sincerity, like saying, 'I'll stake my life on it!'
But Jesus points out the fundamental flaw: we have no ultimate control over our own lives, not even the color of our hair.
We often think 'taking God's name in vain' only means lying under oath. But Jesus is calling us to a much higher standard of reverence in our speech.

Jesus isn't just correcting a misunderstanding of the Old Testament law; he's revealing its deeper intent. The Pharisees had twisted the law, believing that as long as they didn't openly swear by God's name falsely, they were in the clear. Swearing by the 'heavens,' 'earth,' or 'head' was seen as a loophole.
Jesus dismantles this legalistic thinking:
Understand the original words
omnyō · Greek Verb
A solemn appeal to God or something sacred to witness the truth of a statement or the sincerity of a promise. In the Bible, oaths were often used to confirm covenants or provide assurance in legal matters.
kephalē · Greek Noun
The physical head of a person, often used metaphorically in Scripture to signify leadership, authority, or the source of life and identity.
thrix · Greek Noun
A single strand of hair; scriptural references to hair often emphasize God's minute sovereignty and intimate knowledge of His creation, as well as the limits of human power.
Jesus is not abolishing the Old Testament Law regarding oaths, but rather fulfilling its spirit by exposing and correcting the superficial interpretations that had crept in, emphasizing the deep reverence due to God's name in all speech.
c. 5th century BC
Development of Corrupt Oath Practices
During and after the Babylonian Exile, Jewish scribes and Pharisees developed complex and often hypocritical rules about oaths. They distinguished between different types of oaths, believing that some were binding while others, particularly those not invoking God's name directly, were not.
Late 1st century BC - Early 1st century AD
Pharisaic Oath Interpretations Flourish
The Pharisees' teachings became influential, promoting the idea that oaths by the heavens, earth, or one's own head were casual and did not carry the same weight as oaths sworn by God's name. This led to a widespread disregard for the sanctity of speech.
c. AD 27-30— this verse
Jesus Delivers the Sermon on the Mount
Jesus, addressing his disciples and a large crowd, taught on the principles of his kingdom, including a radical reinterpretation of the Law. He directly challenged the corrupt oath-taking practices prevalent among the Jewish leaders and populace.
c. AD 30-33
Jesus' Teachings Spread
News of Jesus' teachings, including his radical stance on oaths and the importance of truthful speech, spread throughout Judea and Galilee, influencing his followers and provoking debate.
This passage shows Abraham requiring his servant to swear by God, emphasizing that oaths are ultimately about invoking God's authority and presence.
Deuteronomy 6:13This verse commands, 'Fear only the Lord your God, and swear by his name,' highlighting that oaths are meant to be made by God alone, aligning with Jesus' correction of common oath practices.
James 5:12This passage directly echoes Jesus' teaching by saying, 'Above all, my brothers and sisters, do not swear—not by heaven or by earth—or by any other oath. Simply let your ‘Yes’ be ‘Yes,’ and your ‘No,’ ‘No,’ to avoid judgment.'
Hebrews 6:16This verse explains that people swear by something greater than themselves to confirm their agreement, underscoring that oaths, even those Jesus corrects, are understood as appeals to a higher authority.
barnesMatthew 5:36: "Neither shalt thou swear by thy head, because thou canst not make one hair white or black."
Neither shalt thou swear by thy head - This was a common oath. The Gentiles also used this oath. To swear by the head was the same as to swear by the life; or to say, I will forfeit my life if what I say is not true. God is the Author of the life, and to swear by that, therefore, is the same as to swear by him. Because thou canst not make one hair white or black - You have no control or ri…

- Again, ye have heard that it was said to the ancients, Thou shalt not perjure thyself: but thou shalt perform to the Lord what thou hast sworn. 34. But I charge you, swear not at all: neither by heaven, for it is the throne of God: 35. Nor by the earth, for it is his footstool: nor by Jerusalem, for it is the city of the great King…
