The word "concept" wasn't used in the sentence that was quoted. The sentence started with the word "it", which could have been referring to Israel or the concept of Israel or both.
It reads to me as referring to the concept of Israel, since the prior sentence was "This extraordinary remark by Bennett lays bare the fundamental flaw in the very concept of Israel". The next sentence starts with "It" and follows with "is not a modern state, defined as a territory and comprising all the various citizens of whatever descent who live within it. It is rather a vicious racist construct, defined absolutely by race, refusing territorial limits, and with an aggressive theocratic overlay that claims tribal superiority over the entire rest of the world."
Murray's defence also highlights that he was referring to the concept of Israel.
I'd be grateful, by the way, if you could tell me exactly what the difference is between Israel and the concept of Israel is and why it matters in this case.
Israel is the state currently defined under and subject to international law.
The concept of Israel is the establishment by public law of a Jewish state in the Land of Israel, which doesn’t belong solely to its citizens, but to the entire Jewish people. The practical expression of this commitment is the Law of Return, which the Knesset passed in 1950. In 1970, Israel took another historic step by granting automatic citizenship not only to Jews, but also to their non-Jewish children, grandchildren, and spouses, and to the non-Jewish spouses of their children and grandchildren.

https://www.theguardian.com/world/2016/feb/02/palestinian-families-homeless-as-israeli-military-demolishes-west-bank-housesWhy else do you think Murray's blog started by talking about the claim that Netanyahu was leader of the whole Jewish world and then moved onto discussing the concept of Israel?
And it doesn't matter with respect to libel.
Simons said that Murray said something. Murray called Simons a liar. Murray did actually say the thing that Simons claimed he said. Therefore Simons is not a liar.
It's not rocket science.
It was a false accusation. cIt's better to withdraw it from any perspective.
In order to call someone a liar and defend yourself in court against libel, the burden of proof is on you to show that your accusation of lying was true - which is why defending yourself against a libel case can be a very costly exercise. Since it is difficult to prove that taking the quote out of context and substituting "Israel" where it referred to the concept of Israel's theocratic overlay, amounts to lying, Murray has been correctly advised to withdraw the accusation of lying.
Read the defence documents - Murray's defence denies Simons' paragraph 5 i.e the words complained of. Murray's defence also claims that the context of the words is important.
https://www.craigmurray.org.uk/archives/2017/09/jake-wallis-simons-v-craig-murray/Also, Simons' libel case is about Murray claiming in his blog that Simons is part of a campaign to discredit Palestinian supporters as anti-semites. So it doesn't just concern the accusation of lying.
