Athelstan, c.895-939, public domain
To those who rule and lead us on earth,
you, sovereign Master,
have given authority and kingship.
Grant them, Lord, the health, peace, concord, and stability
to use aright the sovereignty you have bestowed on them.
For you, King of Heaven, you it is that give mortal men
glory, honor, and power over what is on earth.
Lord, make their counsels conform to what is good and pleasing to you,
that using with reverence, peacefully, gently,
the power you have given them,
they might find favor with you.
Clement of Rome, c.30- 99 Bishop, first Apostolic Father

Daniel answered and said:
Blessed be the name of God forever and ever,
to whom belong wisdom and might.
He changes times and seasons;
he removes kings and sets up kings;
he gives wisdom to the wise
and knowledge to those who have understanding
