Charut appears exactly once in the whole Tanakh, and it is spent on the most exclusive object in it: "the tablets were the work of God, and the writing was the writing of God, charut upon the tablets" (Exodus 32:16). A hapax legomenon, the grammarians call that, a one-time word. The only engraving Scripture ever names with it is the engraving HaShem did Himself.

The KJV says "graven," the modern versions say "engraved," and the accuracy is fine as far as it goes. What no English can show is the singularity, that the word itself is as unrepeated as the act, or the wordplay the sages refused to leave alone: read not charut, engraved, but cherut, freedom (Avot 6:2). The same letters. Freedom cut into stone.

And the word's loneliness is the point of its story. What is engraved on stone sits outside you, and stone breaks; the tablets did, at the foot of the mountain, in the hour of the calf. So the promise moved the writing: not charut on tablets but written on the heart (Jeremiah 31:33), where "write them on the tablet of your heart" (Proverbs 3:3) had always been pointing. The one-time word was waiting for a one-time surgery.
