There shall not a hand touch it, but he shall surely be stoned, or shot through; whether it be beast or man, it shall not live: when the trumpet sounds long, they shall come up to the mount.
All Commentaries on Exodus 19:13 Go To Exodus 19
Gregory the Theologian
AD 390
But if any is an evil and savage beast and altogether incapable of taking in the subject matter of contemplation and theology, let him not hurtfully and malignantly lurk in his den among the woods, to catch hold of some dogma or saying by a sudden spring and to tear sound doctrine to pieces by his misrepresentations. But let him stand yet afar off and withdraw from the mount, or he shall be stoned and crushed and shall perish miserably in his wickedness.
