The first mention of dung in the Bible is in connection with the sacrificial rites. The sacred law required that the dung, along with other parts of the animal, should not be burned on the altar but should be burned outside the camp (Exod 29:14; Lev 4:11-12).
A major disgrace for a Jew was to have one’s carcass treated as dung (2 Kings 9:37). During has been used as fertilizer for centuries. It is recorded in Luke 13:8 and Isa 25:10 that the people of Palestine used it for that purpose. Dry dung was and is often used as fuel (Ezek 4:12-15). Animal dung was used as fuel when it was mixed with straw and dried to a suitable state for heating the simple bread ovens.
Paul used a powerful metaphor with the word “dung” when he made a comparison between his personal knowledge of Christ and those who did not know Christ (Phil 3:8). The word is used also in Scripture to indicate symbolically the degradation to which a person or a nation might fall (2 Kings 9:37; Jer 8:2).
