Hebrews 12:20

For they could not bear what was commanded: “If even an animal touches the mountain, it must be stoned.” ¹ 

because they could not bear what was commanded: "If even an animal touches the mountain, it must be stoned."

For they could not bear the command, "IF EVEN A BEAST TOUCHES THE MOUNTAIN, IT WILL BE STONED."

They staggered back under God’s command: "If even an animal touches the mountain, it must be stoned to death."

When they heard the words--"If an animal touches the Mountain, it's as good as dead"--they were afraid to move.

For the order which said, If the mountain is touched even by a beast, the beast is to be stoned, seemed hard to them;

(For they could not endure the order that was given, "If even an animal touches the mountain, it shall be stoned to death."

(For they could not endure what was commanded: "And if so much as a beast touches the mountain, it shall be stoned or shot with an arrow."

For they could not bear what was commanded: “If even an animal touches the mountain, it must be stoned.” ¹
