KJV Isa 6:3 And one cried unto another, and said, Holy, holy, holy, [is] the LORD of hosts: the whole earth [is] full of his glory.

Hebrew literal translation: his glory is the fullness of the whole earth

KJV Isa 6, 9 And he said, Go, and tell this people, Hear ye indeed, but understand not; and see ye indeed, but perceive not.
10 Make the heart of this people fat, and make their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their heart, and convert, and be healed.

The difference between those inside and those standing outside

Mat 13 10 Why speakest thou unto them in parables? 11 He answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given.

12 For whosoever hath, to him shall be given, and he shall have more abundance: but whosoever hath not, from him shall be taken away even that he hath.

13 Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand. 14 And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall hear, and shall not understand; and seeing ye shall see, and shall not perceive:

15 For this people’s heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them.

16 But blessed are your eyes, for they see: and your ears, for they hear. 17 For verily I say unto you, That many prophets and righteous men have desired to see those things which ye see, and have not seen them; and to hear those things which ye hear, and have not heard them. 18 Hear ye therefore the parable of the sower.
