But the king will rejoice in God; all who swear by God will glory in him, while the mouths of liars will be silenced. (NIV)
But the king shall rejoice in God; everyone who swears by Him [that is, who binds himself by God's authority, acknowledging His supremacy, and devoting himself to His glory and service alone; every such one] shall glory, for the mouths of those who speak lies shall be stopped. (AMP)
But the king shall rejoice in God; every one that sweareth by him shall glory: but the mouth of them that speak lies shall be stopped. (KJV)
