New Defender's Study Bible Notes
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.
1:14 obedient children. Read “children of obedience” (compare Ephesians 5:8; contrast Ephesians 2:2).
1:14 fashioning. “Fashioning” is the same word in the Greek as “conforming.” Its only other use is in Romans 12:2: “Be not conformed to this world.”
1:15 conversation. “Conversation” includes not only our speech, but all aspects of conduct.
1:16 it is written. See Leviticus 11:44-45.
