Parallel
Ezekiel 21:15
Brenton's English Septuagint · Berean Standard Bible
that thou mayest slay victims; be sharpened that thou mayest be bright, ready for slaughter, slay, set at nought, despise every tree.
So that their hearts may melt and many may stumble, I have appointed at all their gates a sword for slaughter. Yes, it is ready to flash like lightning; it is drawn for slaughter.
