Remember therefore how thou hast received and heard, and hold fast, and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee.
Textus Receptus (TR) - Revelation 3:3 >Μνημόνευε οὖν πῶς εἴληφας καὶ ἤκουσας, καὶ τήρει, καὶ μετανόησον. Ἐὰν οὖν μὴ γρηγορήσῃς, ἥξω ἐπί σε ὡς κλέπτης, καὶ οὐ μὴ γνῷς ποίαν ὥραν ἥξω ἐπί σε.
