2 Samuel 22:30

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

This declaration belongs to a song David composed while Saul was pursuing him to take his life. The song recounts his dangers and deliverances. It expresses his unwavering trust in God as his merciful preserver through severe trials and gives praise to God. It means that running through a troop and leaping over a wall was accomplished not by his own strength but by God's enabling help to overcome enemies and barriers.
