Luke 17:6

εἰ ἔχετε. εἰ with pres. in protasis, the imperf. in apodosis with ἄν. Possession of faith already sufficient to work miracles is here admitted. In Mt. the emphasis lies on the want of such faith. Another instance of Lk.'s desire to spare the Twelve. συκαμίνῳ, here only in N.T. = συκομορέα, Luke 19:4, the fig mulberry tree (vide there). A tree here, a mountain in Mt.; and the miraculous feat is not rooting it out of the earth but replanting it in the sea a natural impossibility. Pricaeus cites a classic parallel: τὸ πέλαγος πρότερον οἴσει ἄμπελον.
