2 Samuel 22:29 (KJV)

I was also upright before him, and have kept myself from mine iniquity.

Therefore the LORD hath recompensed me according to my righteousness; according to my cleanness in his eye sight.

With the merciful thou wilt shew thyself merciful, and with the upright man thou wilt shew thyself upright.

With the pure thou wilt shew thyself pure; and with the froward thou wilt shew thyself unsavoury.

And the afflicted people thou wilt save: but thine eyes are upon the haughty, that thou mayest bring them down.

For by thee I have run through a troop: by my God have I leaped over a wall.

As for God, his way is perfect; the word of the LORD is tried: he is a buckler to all them that trust in him.

For who is God, save the LORD? and who is a rock, save our God?

God is my strength and power: and he maketh my way perfect.

He maketh my feet like hinds' feet: and setteth me upon my high places.
