THE EPISTLE OF PAUL THE APOSTLE TO THE HEBREWS - Chapter 12 - Verse 20

The meaning is not that the commands themselves were intolerable, but that the manner in which they were communicated inspired a terror which they could not bear. They feared that they should die. Ex 20:19

And if so much as a beast touch the mountain, it shall be stoned. Ex 19:13. The prohibition was, that neither beast nor man should touch it on pain of death. The punishment was to be either by stoning, or being "shot through."

Or thrust through with a dart. Ex 19:13. "Or shot through." This phrase, however, though it is found in the common editions of the New Testament, is wanting in all the more valuable manuscripts; in all the ancient versions; and it occurs in none of the Greek ecclesiastical writers, with one exception. It is omitted now by almost all editors of the New Testament. It is beyond all doubt an addition of later times, taken from the Septuagint of Ex 19:13. Its omission does not injure the sense.

{b} "And if" Ex 19:13,16
