Hebrews 11:33-34 NLT
By faith these people overthrew kingdoms, ruled with justice, and received what God had promised them. They shut the mouths of lions, [34] quenched the flames of fire, and escaped death by the edge of the sword. Their weakness was turned to strength. They became strong in battle and put whole armies to flight.

Hebrews 6:18 NLT
So God has given both his promise and his oath. These two things are unchangeable because it is impossible for God to lie. Therefore, we who have fled to him for refuge can have great confidence as we hold to the hope that lies before us.

Hebrews 1:8-9
But of the Son he says,
“Your throne, O God, is forever and ever, the scepter of uprightness is the scepter of your kingdom. You have loved righteousness and hated wickedness; therefore God, your God, has anointed you with the oil of gladness beyond your companions.”
