Parallel
Exodus 12:13
Swete's Septuagint · Berean Standard Bible
καὶ ἱστᾶι τὸ αἷμα ὑμῖν ἐν σημείῳ ἐπὶ τῶν οἰκιῶν ἐν αἷς ὑμεῖς ἐστὲ ἐκεῖ· καὶ ὄψομαι τὸ αἷμα, καὶ σκεπάσω ὑμᾶς, καὶ οὐκ ἔσται ἐν ὑμῖν πληγὴ τοῦ ἐκτριφθῆναι ὅταν παίω ἐν γῇ Αἰγύπτῳ.
The blood on the houses where you are staying will be a sign; when I see the blood, I will pass over you. No plague will fall on you to destroy you when I strike the land of Egypt.
