Ezra 10:8: Verse 8
All his substance should be forfeited - To the use of the temple.
So the Septuagint understood the place: Αναθεματισθησεται πασα ἡ ὑπαρξις αυτου, "All his substance shall be devoted to a holy use."
Himself separated - Excommunicated from the Church of God, and exiled from Israel.
