Four of the five sacred relics of the Nephites that I discussed have fairly clear parallels to their Old World counterparts: the interpreters like the Urim and Thummin, the metal plates like the stone tablets with the law, the sword of Laban as a symbol of authority like the rod of Aaron, and the Nephite breast plate like the High Priest's breastplate. The least obvious and most interesting parallel deals with the pot of manna preserved in the Ark of Solomon's temple.
A possible Nephite parallel is introduced using language that may have been crafted to serve as a parallel to the sacred manna which, according to Exodus 16:13-15, was discovered in the desert in the morning and
Lehi's Liahona serves as a fitting parallel to the pot of manna, a symbol of the Lord's mercy and deliverance. And like manna, it wasn't a gift to be taken for granted, but could quit functioning as a result of rebellion.
With relics to match each of the relics of the Ark of the Covenant, the Nephites could have a reasonable imitation of Solomon's temple in spirit and function, making the Holy of Holies an suitably sacred place.
There's more to the Liahona that we should consider. Long ago I had correspondence with a man studying to become a Rabbi who was also impressed with the Book of Mormon as an authentic ancient Jewish text. He wasn't LDS and I'm not sure what became of his interest, but he offered his rough analysis of the word Liahona, opining that it was good Hebrew. He said the name (lamed-yud-hey-vav-nun-alef in Hebrew) is related to known Hebrew words with relevant meanings:
- LIA (lamed-yud-hey), Strongs 3914: something round; a wreath
- LAWAH (lamed-vav-hey), Strongs 3867: to bind around; to wreathe; to start or stop
- LON (lamed-vav-nun), Strongs 3885, from LAWAH: to abide, to dwell, to remain or to continue.
Curci has much more to say about the term Liahona and its aptness in the Book of Mormon record. Just one of many cool, ancient, and increasingly plausible elements in the Book of Mormon.
