Isaías 21:7

7. Chariot… horsemen… asses… camels The first report is, the approach of a long procession, headed by horsemen, seen in perspective as two, a column of two, or two abreast, then successions of chariots drawn by asses and camels, which animals were used in ancient campaigns for different purposes, as both Herodotus and Xenophon testify of the Persians. (Xenophon, Cyrop., Isaiah 4:3.) They not only carried baggage and provisions, but were taken into battle to throw the enemy into confusion by fright, etc. The watchman not only saw, but he listened listened with intense listening; yet he heard nothing, so still was the approach.
