What I tell you in darkness, that speak in light: and what you hear in the ear, that preach upon the housetops.
All Commentaries on Matthew 10:27 Go To Matthew 10
John Chrysostom
AD 407
The point is not that Jesus was literally whispering into their ears or speaking in physical darkness. Rather, he was here pressing a strong figure of speech. He was conversing with them quietly and alone in a small corner of Palestine. In contrast with this tone of voice, they would soon be preaching with a boldness of speech that would in due time be conferred upon them. The metaphor of whispering in the ear in a dark place, in this present quietness, is contrasted with what is to come. For they were soon to be commissioned to speak not to one or two or three cities but to the whole world. They would soon be traversing land and sea, amid inhabited countries and across deserts, addressing both princes and tribes, philosophers and orators, telling it like it is with an open face and with all boldness of speech.
