Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ ἡ χεὶρ τῶν μαρτύρων ἔσται ἐπ᾿ αὐτῷ ἐν πρώτοις θανατῶσαι αὐτόν καὶ ἡ χεὶρ παντὸς τοῦ λαοῦ ἐπ᾿ ἐσχάτων καὶ ἐξαρεῖς τὸν πονηρὸν ἐξ ὑμῶν αὐτῶν
The hands of the witnesses shall be the first in putting him to death, and after that, the hands of all the people. So you must purge the evil from among you (note: Cited in 1 Corinthians 5:13).
