20 for they could not stand that which was commanded, "If even an animal touches the mountain, it shall be stoned{TR adds "or shot with an arrow" [see Exodus 19:12-13]};"
You shall set bounds to the people round about, saying, 'Be careful that you don't go up onto the mountain, or touch its border. Whoever touches the mountain shall be surely put to death. No hand shall touch him, but he shall surely be stoned or shot through; whether it is animal or man, he shall not live.' When the trumpet sounds long, they shall come up to the mountain."
Now we know that whatever things the law says, it speaks to those who are under the law, that every mouth may be closed, and all the world may be brought under the judgment of God. Because by the works of the law, no flesh will be justified in his sight. For through the law comes the knowledge of sin.

Commentary on Hebrews 12 Matthew Henry Commentary
Chapter 12
The apostle, in this chapter, applies what he has collected in the chapter foregoing, and makes use of it as a great motive to patience and perseverance in the Christian faith and state, pressing home the argument,
Hbr 12:1-3
Here observe what is the great duty which the apostle urges upon the Hebrews, and which he so much desires they would comply with, and that is, to lay aside every weight, and the sin that did so easily beset them, and run with patience the race set before them. The duty consists of two parts, the one preparatory, the other perfective.
Hbr 12:4-17
Here the apostle presses the exhortation to patience and perseverance by an argument taken from the gentle measure and gracious nature of those sufferings which the believing Hebrews endured in their Christian course.
Hbr 12:18-29
Here the apostle goes on to engage the professing Hebrews to perseverance in their Christian course and conflict, and not to relapse again into Judaism. This he does by showing them how much the state of the gospel church differs from that of the Jewish church, and how much it resembles the state of the church in heaven, and on both accounts demands and deserves our diligence, patience, and perseverance in Christianity.
