ever tried reading the TaNaCH without reading Jesus into it?
Yes of course; it is the best way to understand a book, by starting at the beginning.
Just reading what it says and taking it at face value without the lens of the NT?
If you apply the lens of the whole of the New Testament, it ends up being more confusing; as Christianity (Paul, John, Simon) create a manner in which to assess it by, that doesn't necessarily fit within the text, and defiles the Law.
So by reading the Tanakh first, understanding the Law, and then the prophets, you see how somethings are required to make it fit together.
A servant will be sent, who shall be put to death; yet later receive the kingdom....
Because they help establish a snare, and line across Israel, that shall catch out those who swear falsely, and steal what isn't theirs, as they're quick to the spoils (If you know the Tanakh well enough, you may understand that comes from the Tanakh first, Yeshua after, as you can't really see it in reverse).
Can go into great detail of using the Tanakh's prophecy to show a line of trajectory, of what is required to fulfill it.
Sometimes ponder if the New Testament is even totally made up by the Jews or YHVH, as it fits so cleverly with the prophetic text, it is beyond normal comprehension, and takes a Bible word search to realize how it is put together.
