While pondering one of the most well-known and beloved Psalms, I suddenly recognized something. It is the Lord's rod and staff that can give us comfort when we are traveling through the valley's of mortality. What do they represent? I think it would be appropriate to draw a connection to the iron rod seen in Lehi's dream. The Lord has provided us with His word, which will be a comfort and a guide if we will cling to it with all our strength.
