And that is why you aren’t placed in a position of trust/confidence.
If those people wanted help from other people, they would ask their friends, neighbors, etcetera. But they are asking God. Not only that, but they are going out of their way to travel to THE Holy Site in order to deliver their message.
While I have no doubt you mean well, the simple truth is that Halakha (the Jewish law) specifically and explicitly forbids it. It’s not your note, and you are not God, so you have no right whatsoever to read it. In fact, its akin to taking the note from God’s hands as He reads it, and I don’t think noble intentions are enough to excuse being directly rude to God.
Maybe people could help others, but at what price? By desecrating their holy places, violating their laws, and disrespecting their deity? I’m sure they’d be thankful for your blasphemy.
