Mathew 21:42 meaning

[YCGP]

So they took him and cast him out of the vineyard and killed him.
40
Therefore, when the owner of the vineyard comes, what will he do to those vinedressers?”
41
They said to Him, “He will destroy those wicked men miserably, and lease his vineyard to other vinedressers who will render to him the fruits in their seasons.”
42
Jesus said to them, “Have you never read in the Scriptures: ‘The stone which the builders rejected Has become the chief cornerstone. This was the LORD’s doing, and it is marvelous in our eyes’?

What exactly is the Lord's doing here? It does not mean the murdering does it?

Jesus was talking about the demise of Israel as a nation. They were the ones who the parable was aimed at. God is the owner of the "Vineyard". Israel suffered utter destruction at the hands of the Romans. The gospel went to the gentiles who are the "other vinedressers"
