Psalm 7:12-17

If a man does not repent, God will whet his sword; he has bent and readied his bow; he has prepared for him his deadly weapons, making his arrows fiery shafts. Behold, the wicked man conceives evil and is pregnant with mischief and gives birth to lies. He makes a pit, digging it out, and falls into the hole that he has made. His mischief returns upon his own head, and on his own skull his violence descends. I will give to the LORD the thanks due to his righteousness, and I will sing praise to the name of the LORD, the Most High.
