Man’s first form of trading was woman exchange; it long preceded horse trading.  Trade by barter followed seizure by raids.  Silent barter was first used, securing plazas with fetishes and exchanging grain or animals. Writing had its origin in trade records.  The early traders were women; they were employed as spies, carrying on commerce as a side line.  International commerce contributes to peace and brotherhood.  Commerce, linked with adventure, led to exploration and discovery.  Commerce quickly became the most potent influence in the spread of cultural civilization. 
Commerce appeared ca. 8000 B.C. , when the slowly increasing aridity of the highland regions of central Asia began to drive the Andites to the river bottoms and the seashores.  The Dravidians of India and Sumerians were among the earliest peoples to engage in an extensive export and import business.  There was great commercial relationships between China and Mesopotamia, but this trading ended on 3,000 B.C.  Mediterranean sea-borne commerce was in full swing about 2500 B.C.  Some of man’s very early maritime commerce was established on the inland lakes of Mediterranean. 
Jesus’ advice to rich man on wealth derived from commerce was to apply fairness and honest treatment to deserve wages for his services.  Jesus never meddled with others’ temporal business, but what he never accepted was covetousness.
