Exodus 10:21
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
And the Lord said unto Moses, Stretch out thine hand toward heaven, that there may be darkness over the land of Egypt, even darkness which may be felt (note: Heb. that one may feel darkness).
Then the LORD said to Moses, “Stretch out your hand toward heaven, so that darkness may spread over the land of Egypt—a palpable darkness.”
