Exodus 12:7
Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ λήμψονται ἀπὸ τοῦ αἵματος καὶ θήσουσιν ἐπὶ τῶν δύο σταθμῶν καὶ ἐπὶ τὴν φλιὰν ἐν τοῖς οἴκοις ἐν οἷς ἐὰν φάγωσιν αὐτὰ ἐν αὐτοῖς
They are to take some of the blood and put it on the sides and tops of the doorframes (note: Literally on the two doorposts and on the lintel; similarly in verses 22 and 23) of the houses where they eat the lambs.
