Psalms 18:26-30

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

For thou wilt save the afflicted people; but wilt bring down high looks.

For thou wilt light my candle: the LORD my God will enlighten my darkness.

For by thee I have run through a troop; and 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 those that trust in him.
