Hebrews 12:21

Heb. 12:21. And so terrible was the sight, (that) Moses said, I exceedingly fear and quake:)

Blank Bible:

vid No. 81 Moses said] i.e., he wrote this of himself as he gives account in the 19 of Exod. 16 v (Exodus 19:16) that all the people that was in the camp trembled including himself for he was then in the Camp. This is something after the same manner as God is said in the first Chap. at the 8 v. to say unto is son thy throne O God is forever and ever, etc. - i.e. David speaking by the spirit of God said so of the son H see last vac. p. 30 (?)

Notes on the Bible:

[135] Hebrews 12:21. "And so terrible was the sight, that Moses said, I exceedingly fear and quake." The place referred to seems to me to be, Deuteronomy 9:18-19, "I fell down, for I was afraid of the anger and hot displeasure," etc. God at that time manifested his displeasure by the extraordinary burning in the mount. See verse 15.
