Matthew 25:46 & Aionios

[DavidFord]

the Septuagint, the Greek translation of the Hebrew OT that was quoted by Jesus and all NT authors

Cave 4 of the Qumran caves revealed the existence of a Hebrew textual tradition more-similar to the LXX than to the Masoretic.  Jesus and the NT authors spoke Aramaic and quoted from Semitic sources, not the LXX.
