Question

On the night the war began, in the prime minister’s speech he said that “the people of Iran and the people of Israel were true friends already from the days of Cyrus the Great.” Until now we didn’t have time to think about it because of the chain of events, but now that the guns of war have fallen silent there is a bit of free time, and I wanted to ask: who is Cyrus the Great? And what is his role, significance, and connection to the Jews?
