Exodus 13:15
Swete's Septuagint · Berean Standard Bible
ἡνίκα δὲ ἐσκλήρυνεν Φαραὼ ἐξαποστεῖλαι ἡμᾶς, ἀπέκτεινεν πᾶν πρωτότοκον ἐν γῇ Αἰγύπτῳ ἀπὸ πρωτοτόκων ἀνθρώπων ἕς πρωτοτόκων κτηνῶν διὰ τοῦτο ἐγὼ θύω πᾶν πρωτότοκον τῷ κυρίῳ, πᾶν διανοῖγον μήτραν, τὰ ἀρσενικά, καὶ πᾶν πρωτότοκον τῶν υἱῶν μου λυτρώσομαι.
And when Pharaoh stubbornly refused to let us go, the LORD killed every firstborn in the land of Egypt, both of man and beast. This is why I sacrifice to the LORD the firstborn male of every womb, but I redeem all the firstborn of my sons.’
