Researching the Book of Enoch got me paying attention to Sumerian and Akkadian cuneiform script and its meanings and their use in scriptures and understanding of things of God. One treasure I found is the original symbol of the cross and what it means - https://en.wiktionary.org/wiki/đ’ˆ¦ The cross symbol means a settlement of account or a tax and similarly means a sacrifice which settles with God. It also came to be associated with those whose role was to settle things between God (or gods) and men - mediating. Such people typically offered sacrifices to appease gods before seeking oracles. So the lamb of God having such a symbol in being crucified on a cross shows the open mind that He is a sacrifice to settle things with God.
