Dung
The uses of dung were two-fold--as manure and as fuel. The manure consisted either of straw steeped in liquid manure, (Isaiah 25:10) or the sweepings, (Isaiah 5:25) of the streets and roads, which were carefully removed from about the houses, and collected in heaps outside the walls of the towns at fixed spots--hence the dung-gate at Jerusalem--and thence removed in due course to the fields. The difficulty of procuring fuel in Syria, Arabia and Egypt has made dung in all ages valuable as a substitute. It was probably used for heating ovens and for baking cakes, (Ezra 4:12,15) the equable heat which it produced adapting it pecularily for the latter operation. Cow's and camels dung is still used for a similar purpose by the Bedouins.
