Here are two awesome videos about Hebrew alphabet symbolism. The top one shows how the Hebrew Alphabet is hidden in 1 Nephi of the Book of Mormon Another Testament of Jesus Christ. Natasha Pizorno is the presenter. Her book pictured below goes deeper into this topic.
The bottom one features Donna Nielsen, author of Beloved Bridegroom. She mentions a few of the Hebrew alphabet letters, namely alef, symbolized by the ox, and mem, symbolized by a zig zag wave of water. She also explains several verses in Isaiah. This is all so amazing! If you want to know more about diving deeper into the scriptures, I highly recommend learning about Scripture Notes here.
