These verses contain a scene of extraordinary joy at the missionary reunion of Ammon, his brothers, and their close friend Alma. This same Ammon who was so joyful as he gloried in his God (Alma 26) was now so overcome with joy that his physical strength gave out, and he fell to the earth. For more about this loss of physical strength when immersed in the Spirit and the joy of God, see commentary at 1 Nephi 1:5–20.
