'Girding' in the Bible

verily, verily, I say to thee, When thou wast younger, thou wast girding thyself and wast walking whither thou didst will, but when thou mayest be old, thou shalt stretch forth thy hands, and another will gird thee, and shall carry thee whither thou dost not will;'

Stand therefore, girding your waist with truth, and putting on the breastplate of righteousness,

Wherefore girding up the loins of your mind, be sober and set your hope perfectly on the grace that is to be brought unto you at the revelation of Jesus Christ;
