gird up
1 Peter 1:13
1:13 gird up. This expression, meaning to be serious and thoughtful rather than shallow and flippant in attitude, comes from the custom of gathering up one’s flowing robe (the customary dress of the day, even for men) and tying it up around the loins, in order to free the feet and legs for running or for working at certain manual tasks. Note Luke 12:35; 17:8; Acts 12:8.
