Moffat had hitherto taught the natives through an interpreter. He now determined not only to master their language, but to get to know all about their habits and customs, so as to be able to lay hold of them more forcibly. He not only preached the Word in their native tongue, but set up in type and printed the Gospel of St. Luke and some hymns. Then he followed on with the other Gospels and also the Epistles, till the entire of the New Testament was translated into their language.
