What are the bone markers (tsiyyun) in Ezekiel 39:15?

A tsiyyun (צִיּוּן, H6725) is a waypost — a practical marker erected over a human bone to guide the burial detail to the spot. It is not a tribute, not a memorial, and not permanent.

The clearest way to see this is to count. H6725 appears exactly three times in the entire Old Testament, and in no case does it function as a monument to the honored dead.

"Then he said, 'What is that tsiyyun I see?' The men of the city told him, 'It is the grave of the man of God who came from Judah...'" (2 Kings 23:17)

Here Josiah spots the marker and asks what it is. He is told it marks a prophet's tomb — and precisely because he identifies the bones inside as belonging to a man of God, he orders them left alone. The tsiyyun locates a grave so it can be respected, not celebrated.

"Set up tsiyyunim for yourself, make yourself road markers; set your heart toward the highway, the road by which you went." (Jeremiah 31:21)

Here the word is plural and the context is practical navigation. The returning exiles need wayposts and road markers to find their way home. The terms paired with tsiyyunim — H8564 tamrurim ("signposts") and H4546 mesillah ("highway") — confirm the navigational register. These are not honorific; they are functional.

"And when the travelers pass through the land and anyone sees a human bone, he will erect a tsiyyun beside it, until the burial teams have buried it..." (Ezekiel 39:15)

The Ezekiel usage matches the others: a marker erected beside a human bone (H6106 etsem + H120 adam) for a purely functional reason. The Greek Septuagint makes the function explicit. For the tsiyyun at Ezekiel 39:15, the translator chose G4592 σημεῖον — "sign," "functional marker." Four verses earlier, for the qever (H6913, "grave") in Ezekiel 39:11, the same translator used μνημεῖον — "memorial," "tomb." The distinction is deliberate: the burial site is a tomb; the bone-finder's marker is a flag. The Septuagint adds a temporal clause that makes the temporariness explicit: ἕως ὅτου θάψωσιν αὐτό — "until they bury it." The tsiyyun disappears the moment the burial team arrives.

This is Numbers 19:16 applied at battlefield scale. That law declares that any open-field contact with a human bone (עֶצֶם אָדָם, etsem adam, H6106 + H120) causes seven days of ritual uncleanness. Ezekiel 39:15 uses the identical two-word phrase as the trigger: when a search team member sees a human bone, they do not touch it — they mark it and move on. The burial specialists handle the actual interment. The protocol minimizes fresh defilement while ensuring complete coverage of the land.

One note on a common confusion: tsiyyun (H6725, "marker") and Tsiyyon (Zion, the holy mountain) share opening consonants but no etymology and no connection. The tsiyyunim of Ezekiel 39 do not point toward Zion; they point toward bones that need to be buried before the land can be holy.

The tsiyyun is a Levitical purity tool, not a battlefield trophy. The land is defiled by every unburied bone. The flag goes up so the bone goes down — and when the burial is complete, no tsiyyun remains.
