Perhaps you should read the verse prior to the "I know" phrase to find out that it is an angel proclaiming the knowledge not God.
11 And the angel of the LORD called unto him out of heaven, and said, Abraham, Abraham: and he said, Here am I. 12 And he said, Lay not thine hand upon the lad, neither do thou any thing unto him: for now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son from me. Genesis 22:11-12
You certainly may have a point. Based on my very preliminary investigations (less than 15 minutes), the identity of "the angel of the Lord" is rather unclear.
For example, in the following text (Genesis 31:3), he seems to equate himself with God:
Then the
angel of the Lord spoke to me in a dream, saying, ‘Jacob.’ And I said, ‘here I am.’ And He said, lift your eyes now and see, all the rams which leap on the flocks are streaked, speckled, and gray-spotted; for I have seen all that Laban is doing to you.
I am the God of Bethel, where you anointed the pillar and where you made a vow to Me. Now arise, get out of this land, and return to the land of your family.†(Genesis 31:11-13)
On the other hand, we have texts like Exodus 23:20-23:
Behold, I send an Angel before you to keep you in the way and to bring you into the place which I have prepared. Beware of Him and obey his voice; do not provoke Him, for He will not pardon your transgressions; for My name is in Him. But if you indeed obey His voice and do all that I speak, then I will be an enemy to your enemies, and an adversary to your adversaries. For My Angel will go before you and bring you in to the Amorites and the Hittites and the Perizzites and the Canaanites and the Hivites and the Jebusites and I will cut them off.
The general sense of this text is that a
different person is being described.
In any event, I will reformulate my question to lovely by changing the reference to 2 Kings 20.
So I would now ask lovely to have a sentence in her answer that is of the following form: "In 2 Kings 20, when God says "you will not recover" (and later Hez indeed recovers) this does not mean that He has changed his mind (which clearly is the "plain reading") because........."
I believe that in the past lovely has argued that the "you will not recover" statement was true at the time it was made and false later. I think such an argument (whether lovely made it or not) is clearly unworkable.
Lovely, I hope to get back to some of your other questions as time permits.
