After speaking about washing, anointing (13:16–18), laying up treasures in heaven (13:19–21), and serving only one master (13:22–24), Jesus concluded this section of the Sermon by speaking in an aside to the twelve disciples, about God clothing them in garments more glorious than Solomon’s. He was making sure that they knew that He would take care of them. However, like most of Christ’s sayings in this Sermon, there are several levels of meaning here. The word for “raiment”, and [what ye shall] “put on,” here in the Greek is enduo, and we get the word “endow” from that Greek word. When you are endowed you are literally being robed or dressed. One meaning of the verb form of the word is to “invest with clothing,” literally or figuratively. It means to put on clothing, but also means to put on virtues and powers. Here Jesus says, “I will robe you; I will clothe you in garments more glorious than Solomon’s.” This is yet another temple element. Solomon was the great temple builder and king in Jerusalem following the death of his father King David, and as great as Solomon was, he still died. The garment of which Jesus speaks will have eternal value, and if we seek “first the kingdom of God and his righteousness” (13:33), all things shall be added unto us.
Shortly after that, in the Sermon (see 3 Nephi 14:12), Jesus said, “This is the law and the prophets.” So, we may conclude that what we are given in 3 Nephi 13 constitutes the higher “prophets” and Melchizedekian material, just as 3 Nephi 12 had taught the “law” or the Aaronic segments.
