Gird your sword upon your thigh: this means to secure the sword in the sheath, or guard, which hung from a belt around the warrior’s waist. In some languages it will be necessary to make one of three possible adaptations in the expression. First, if the sword is unknown, a local instrument for fighting may be substituted. Second, it may be desirable to use a term for sword which needs reinforcement by the use of a classifier, such as “weapon.” Third, if neither of the above solutions is satisfactory, one may simply translate sword as “your weapon.” If the local weapon is not one that is carried on the hip, further adjustment will be required; for example, “pick up your weapon” or “carry your spear.”

The vocative O mighty one is applied to the king; it can be translated “mighty warrior” (Bible en français courant), “brave man” (see Biblia Dios Habla Hoy), or “warrior king” (New English Bible).

Line b in Hebrew is simply “your glory and majesty”; most connect this with what precedes, in your glory and majesty; Good News Translation takes it as an independent statement, “you are glorious and majestic.” The words can be taken to describe the sword as a symbol of the king’s glory and majesty (see Biblia Dios Habla Hoy “It is your splendid adornment”; Bible en français courant “a symbol of your splendor and your majesty”). The expression in your glory and majesty may sometimes be rendered in reverse order; for example, “you are a great king and do great deeds.”
