King James wording
King James Version
Neither shalt thou swear by thy head, because thou canst not make one hair white or black.THE KEY
The head you swear by cannot certify your promise, because even one hair’s color is beyond your command.
THE MEANING
Your body is not something whose future you can guarantee. Even a hair’s color lies outside your power, so swearing by your head cannot add certainty to what you say.
WHAT THIS UNDOES
It undoes the belief that invoking your own body makes a promise more secure: you do not command the body you invoke.
THE ROOT
δύνασαι
dýnasai
GROWS FROM
δυνα-
dyna-
to be able; to have power
“canst” in this verse is dýnasai. The verse locates the limit in ability: you cannot dictate even a hair’s color, so an oath cannot make your body a guarantee. The same stem names ability and power, revealing the gap between speaking with certainty and possessing control.
ALSO GROWS
dýnamis: power, capacity
δύναμις
This noun names the power the verse shows you do not have over your hair’s color.
dynatos: able, capable
δυνατός
This adjective names capability; the verse makes its absence concrete in the color of one hair.
THE PATTERN
Human speech cannot secure what human power cannot control.
Do not praise yourself over tomorrow, for you do not know what the day will bear.No one has power over the breath to hold in the breath, and no one has power in the day of death. There is no sending away in the war, and wickedness does not slip its owners free.You do not know what tomorrow holds. For what is your life? You are a mist, showing itself for a little while, and then made unseen.THE THREAD
And which of you, by being pulled apart, can add one forearm's length to his stature?Both verses use the same Greek verb for being able: Matthew applies it to changing one hair’s color, while Luke applies it to adding a cubit to one’s stature. Each makes the body a concrete measure of what a person cannot command.
