Exodus 4:23
Rahlfs Septuagint (1935) · Berean Standard Bible
εἶπα δέ σοι ἐξαπόστειλον τὸν λαόν μου ἵνα μοι λατρεύσῃ εἰ μὲν οὖν μὴ βούλει ἐξαποστεῖλαι αὐτούς ὅρα οὖν ἐγὼ ἀποκτενῶ τὸν υἱόν σου τὸν πρωτότοκον
and I told you to let My son go so that he may worship Me. But since you have refused to let him go, behold, I will kill your firstborn son!’”
