Origen
Patristic
c. A.D. 184–253
“Let us learn from Paul, who explains who those "girded" ones are. Hear what he himself says: "Therefore, let your loins be girded with truth." You see, therefore, that Paul knew the girded ones, those who were encircled by the belt of truth. So truth also ought to be our belt, if we have preserved the sacrament of this army and belt. For if truth is the belt by which we are girded for the army of Christ, then whenever we speak a falsehood and a lie proceeds from our mouth, we are ungirded from the army of Christ and loosened from the belt of truth. Therefore, if we are in the truth, we are girded; but if in the false, ungirded. Instead let us imitate those "forty thousand girded men proceeding to the war in the sight of the Lord," and let us always be girded with truth.”
