What does the King James version use for the word Awesome for it's definition?

Answer 1

"DREADFUL"

"...he [Jacob] was afraid, and said, How DREADFUL is this place! This is none other but the House of God, and this is the gate of heaven." (Gen.28:17 KJV)

[NIV]: "He was afraid and said, 'How AWESOME is this place! This is none other than the House of God; this is the gate of heaven."

[Literal Bible]: "And he was afraid and said, How AWESOME is this place! is nothing This except - the House of God, and this {is} the door to the heavens!"

"Strong's Definitions": "yare'" {yaw-ray'}; "a primitive root; to fear; morally, to revere; causatively, to frighten:

Translated elsewhere in the KJV as -- affright, be (make) afraid, dread(-ful), (put in) fear(-ful, -fully, -ing), (be had in) reverence(-end)..." (Strong's Definitions; 'yare')
