Thank you Pastor for reminding us to stay on topic. It's simple enough to enter "shekel" for a search and post the results here for reference. Similarly for silver prices. But the real purpose for doing that, the reason why silver shekels are significant, can easily be overlooked.
The Bible is our most important communication from God. It's important because without it we'd know nothing about Salvation. Value systems cooked up by the likes of
Epicurus or
John Stuart Mill are not based on God's values and could never attain Redemption on our behalf. Jesus did just that. The Bible records those events together with many words from Jesus on a range of topics, helping to educate us, and the values ordained by God explaining why Jesus had to die.
Some of those values relate to different types of person and address compensation to owners when someone is damaged. Others present money values where The Temple is involved. There are different metals used as money from time to time and although we now use fiat currencies—with values determined arbitrarily—metals such as gold or silver (and a few others) still have an actual value.
Godlessness denies us the understanding of our fallen condition from which only blood can rescue. And not just any old blood. Living blood from Christ, above any value we could ever comprehend but spelled out in God's value system which is preserved for us in The Bible. Without it how could we ever know Jesus lived at all? He died to set us free.
