Psalms 144:3

1 Blessed be the LORD my strength, which teacheth my hands to war, and my fingers to fight:

2 My goodness, and my fortress; my high tower, and my deliverer; my shield, and he in whom I trust; who subdueth my people under me.

LORD, what is man, that thou takest knowledge of him! or the son of man, that thou makest account of him!

4 Man is like to vanity: his days are as a shadow that passeth away.

5 Bow thy heavens, O LORD, and come down: touch the mountains, and they shall smoke.

Do read the surrounding verses too, because the context often says more than a single verse.
