Ezekiel 39:15

And the passengers that pass through the land, when any seeth a man's bone, then shall he set up a sign by it, till the buriers have buried it in the valley of Hamongog.

The passengers that pass through the land, when any seeth a man's bone, then shall he set up a sign by it. First, "all the people of the land" engaged in the burying for seven months; then special men were employed, at the end of the seven months, to search for any still left unburied. The passers-by helped them by 'setting up a mark near' any such bones, in order to keep others from being defiled by casually touching them, and that "the buriers" might come and remove them: denoting the minute care to put away every relic of pagan pollution from the Holy Land.
