1 John 2:18-19

Wycliffe Bible

¹⁸ My little sons, the last hour is; and as ye have heard, that antichrist cometh, now many antichrists be made; wherefore we know [whereof we know], that it is the last hour.

¹⁹ They went forth from us, but they were not of us; for if they had been of us, they had dwelt with us; but that they be known, that they be not all of us [but that they be known, that they be not of us].
