a sceptre of righteousness
Forever and Ever
Psalm 45:17 (KJV) I will make thy name to be remembered in all generations: therefore shall the people praise thee for ever and ever.
Ephesians 1:20 Which he wrought in Christ, when he raised him from the dead, and set him at his own right hand in the heavenly places,
21 Far above all principality, and power, and might, and dominion, and every name that is named, not only in this world, but also in that which is to come:
Hebrews 1:8 But unto the Son he saith, Thy throne, O God, is for ever and ever: a sceptre of righteousness is the sceptre of thy kingdom.
