Robertson's Word Pictures (NT)
Trade ye herewith till I come (pragmateusasqe en w erxomai). First aorist middle imperative of pragmateuomai, an old verb from pragma, business. Here only in the N.T. Westcott and Hort in their text read pragmateusasqai, first aorist middle infinitive (-ai and -e were pronounced alike). The infinitive makes it indirect discourse, the imperative direct.
While I am coming is what en w erxomai really means.
