Parallel
Numbers 31:19
Swete's Septuagint · Berean Standard Bible
καὶ ὑμεῖς παρεμβάλετε ἔξω τῆς παρεμβολῆς ἡμέρας· πᾶς ὁ ἀνελὼν καὶ ὁ ἁπτόμενος τοῦ τετρωμένου ἁγνισυήσεται τῆ ἡμέρᾳ τῇ τρίτῃ καὶ τῇ ἡμέρα τῇ ἑβδόμῃ, ὑμεῖς καὶ ἡ αἰχμαλωσία ὑμῶν·
All of you who have killed a person or touched the dead are to remain outside the camp for seven days. On the third day and the seventh day you are to purify both yourselves and your captives.
