Awake, awake; put on your strength, O Zion; put on your beautiful garments, O Jerusalem, the holy city…
If a man put out his strength, he puts on strength, he appears clothed with strength as with a garment. Virgil furnishes us with an illustration: AEneas visits Drepanum in Sicily, and them by various games celebrates the anniversary of his father's death. The combatants with the cestus are described. Dares first shows his face with strength prodigious, and rears himself amid loud murmurs from the spectators. He uplifts his lofty head, presents his broad shoulders, brandishes his arms and beats the air with his fists. And Entellus accepted his challenge, flung from his shoulders his vest, bared his huge limbs, his big bones and sinewy arms, and stood forth of mighty frame in the middle of the field. Forthwith each on his tiptoes stood erect, and undaunted raised his arms aloft in the air. Dares and Entellus, as they put out strength, put on strength. A working-man and a trained athlete, when asleep or otherwise in repose, appear clothed with weakness. All the muscles are relaxed, and the limbs are motionless and apparently powerless, as the parts of a marble statue. But when the athlete is engaged in some bodily exercise, or the working-man is handling his tools and lifting his materials, his appearance is that of one arrayed with power. As he puts out strength he puts on strength, nor can he put it out without putting it on. Adapting the expression of the idea to common utterance, we may read our text, "Put out thy strength, O Zion."
