'Trade' in the Bible

Thus says the Lord,“For three transgressions of Gaza [in Philistia] and for four (multiplied delinquencies)I will not reverse its punishment or revoke My word concerning it,Because [as slave traders] they took captive the entire [Jewish] population [of defenseless Judean border villages, of which none was spared]And deported them to Edom [for the slave trade].

Saying, When will the new moon be gone, so that we may do trade in grain? and the Sabbath, so that we may put out in the market the produce of our fields? making the measure small and the price great, and trading falsely with scales of deceit;

We're eager to trade silver for the poor, a pair of sandals for the needy! We want to mix in some chaff with the grain!"
