Ezekiel 39:17-21 frames Gog's defeat as a sacrifice Yahweh himself officiates — a great zevach that deliberately inverts every element of the Levitical cult. Revelation 19 echoes LXX Ezekiel 39 directly and transforms the sacrifice into a supper, setting up the sharpest contrast in the entire book.
Three times in eight verses Ezekiel calls Gog's burial a Levitical cleansing — H2891 tahar, the Piel of the priests. The bone-marker is Numbers 19 corpse-defilement law at battlefield scale; the LXX confirms the priestly reading with G2511 kathariz?. Renown belongs to Israel, glory belongs to Yahweh, Gog gets neither.
