Again,when the Lord is speaking of His nature we can understand that the interpretation is "literal".
If another verse contradicts what the Lord revealed about His nature then we must take that verse figuratively.
And no one has even attempted to prove that the Lord is not describing His nature at Numbers 23:19.After all,he is contrasting His nature with that of man.He says that He will not lie as does man and he will not change His mind as does man.Another example where the Lord compares His nature to that of man is the following:
""But the LORD said unto Samuel, Look not on his countenance, or on the height of his stature; because I have refused him: for the LORD seeth not as man seeth; for man looketh on the outward appearance, but the LORD looketh on the heart"(1Sam.16:7).
We can know that the Lord does not have to see any "outward appearances" of faith before He can know whether or not a man has faith,and that is because He can look at the heart of man and know.So if we see a verse that seems to be saying that He would not know whether a man feared Him unless He could see an "outward appearance" of that fear,then we know that that verse should not be taken literally. This is an example of such a verse:
"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"(Gen.22:12).
If we use our common sense we can know that this narrative is not to be read employing a wooden literalism.If we take it literally then we can see that the Lord did not know whether or not Abraham feared God until He saw the outward act of Abraham taking the knife to slay his son,Isaac.
And that directly contradicts what the Lord Himself said about His nature.
