Revelation 2:23
Patriarchal Greek New Testament (1904) · Berean Standard Bible
καὶ τὰ τέκνα αὐτῆς ἀποκτενῶ ἐν θανάτῳ, καὶ γνώσονται πᾶσαι αἱ ἐκκλησίαι ὅτι ἐγώ εἰμι ὁ ἐρευνῶν νεφροὺς καὶ καρδίας, καὶ δώσω ὑμῖν ἑκάστῳ κατὰ τὰ ἔργα ὑμῶν.
Then I will strike her children dead, and all the churches will know that I am the One who searches minds and hearts, and I will repay each of you according to your deeds.
