Parallel
Numbers 19:12
Rahlfs Septuagint (1935) · Berean Standard Bible
οὗτος ἁγνισθήσεται τῇ ἡμέρᾳ τῇ τρίτῃ καὶ τῇ ἡμέρᾳ τῇ ἑβδόμῃ καὶ καθαρὸς ἔσται ἐὰν δὲ μὴ ἀφαγνισθῇ τῇ ἡμέρᾳ τῇ τρίτῃ καὶ τῇ ἡμέρᾳ τῇ ἑβδόμῃ οὐ καθαρὸς ἔσται
He must purify himself with the water on the third day and on the seventh day; then he will be clean. But if he does not purify himself on the third and seventh days, he will not be clean.
