4231 pragmateúomai (from 4229 /prágma, "a necessary matter, what is pragmatic") – properly, the ancient mercantile term for trading (exchanging) to make gain, i.e. to do business (barter etc.); trading, exchanging (leveraging) one thing for another to make a legitimate gain; (figuratively) "to bear much fruit" (cf. Jn 15:2f), i.e. the opposite of being fruitless because refusing to make trades by "playing it safe."

4231 (pragmateuomai) means "turning something over," making a good trade – i.e. "to good account . . . to administrate, manage profitably the capital at your disposal" (C. Spicq, 3, 151).

[See also 4230 /pragmateía ("trades") – i.e. exchanges negotiated and transacted as business (personal or official).]
