'Merchants' in the Bible

So Abraham listened to Ephron [and agreed to his terms]; and he weighed out for Ephron the [amount of] silver which he had named in the hearing of the Hittites: four hundred shekels of silver, according to the weights current among the merchants.

So Judah's brothers listened to him. As the Midianite merchants were passing through, they extracted Joseph from the cistern and sold Joseph for 20 pieces of silver to the Ishmaelites, who then took Joseph down to Egypt.
