KING RICHARD: Not all the water in the rough rude sea
Can wash the balm off from an anointed king.
The breath of worldly men cannot depose
The deputy elected by the Lord.
For every man that Bolingbroke hath pressed
To lift shrewd steel against our golden crown,
God for His Richard hath in heavenly pay
A glorious angel. Then, if angels fight,
Weak men must fall, for heaven still guards the right.

William Shakespeare (1564-1616) English dramatist and poet

Richard II, Act 3, sc. 2, l. 55ff (3.2.55) (1595)

Richard makes his case for the Divine Right of Kings. He is then immediately informed that the non-angelic armies he was counting on to fight Bolingbroke aren't coming.
