Yes, I’ve been pondering the latter, myself. Especially recently (last few years).
I was reading Deuteronomy about the punishments for Israel’s disobedience, where a failure to repent would increase the judgment 7 fold. First time was 70 years. Second time was 490 years.
I got curious where 7 times 490 would end up if it began at the fall of Jerusalem in 70 AD. I calculated it to 1967, when Jerusalem was recaptured.
