Hebrews 12:18

For ye are not come unto the mount that might be touched, and that burned with fire, nor unto blackness, and darkness, and tempest,

For - The fact that we are not under the law, but under the glorious privileges of the Gospel is why especially the Hebrew Christians should 'look diligently,' etc. (Hebrews 12:15).

Are not come, [ proseleeluthate (G4334)] - 'have not come near to.' Alluding to Deuteronomy 4:11, "Ye came near

... and the mountain burned with fire ... clouds, and thick darkness." 'In your coming near unto God, it has not been to,' etc.

The mount. 'Aleph (') A C, Vulgate, omit "the mount." "The mount" must be supplied from Hebrews 12:22.

That might be touched - palpable and material. Moses alone was allowed to touch it (Exodus 19:12-2). The Hebrews drew near to the material Sinai with material bodies; we to the spiritual mount in the spirit. The "darkness" was that of the clouds hanging round the mount; the "tempest" accompanied the thunder.
