Hebrews 12:19-21

Young's Literal Translation

¹⁹ and a sound of a trumpet, and a voice of sayings, which those having heard did entreat that a word might not be added to them,

²⁰ for they were not bearing that which is commanded, `And if a beast may touch the mountain, it shall be stoned, or with an arrow shot through,'

²¹ and, (so terrible was the sight,) Moses said, `I am fearful exceedingly, and trembling.'
