'Trade' in the Bible

And having called his own ten bondmen, he gave to them ten minas, and said to them, Trade while I am coming.

and because they were of the same trade abode with them, and wrought. For they were tent-makers by trade.

For we do not, as the many, make a trade of the word of God; but as of sincerity, but as of God, before God, we speak in Christ.
