2 Samuel 22:25

For I have kept the LORD’s ways,

and have not wickedly departed from my God.

For all his ordinances were before me.

As for his statutes, I didn’t depart from them.

I was also perfect toward him.

I kept myself from my iniquity.

With the merciful you will show yourself merciful.

With the perfect man you will show yourself perfect.

With the pure you will show yourself pure.

With the crooked you will show yourself shrewd.

You will save the afflicted people,

but your eyes are on the arrogant, that you may bring them down.
