Psalms 140:7-10   7. O GOD the Lord, the strength of my salvation, thou hast covered my head in the day of battle. 8. Grant not, O LORD, the desires of the wicked: further not his wicked device; lest they exalt themselves. Selah. 9. As for the head of those that compass me about, let the mischief of their own lips cover them. 10. Let burning coals fall upon them: let them be cast into the fire; into deep pits, that they rise not up again.

Psalms 21:7-11   7. For the king trusteth in the LORD, and through the mercy of the most High he shall not be moved. 8. Thine hand shall find out all thine enemies: thy right hand shall find out those that hate thee. 9. Thou shalt make them as a fiery oven in the time of thine anger: the LORD shall swallow them up in his wrath, and the fire shall devour them. 10. Their fruit shalt thou destroy from the earth, and their seed from among the children of men. 11. For they intended evil against thee: they imagined a mischievous device, which they are not able to perform.
