21 - Domine, in virtute tua

1  The King shall rejoice in your strength, O Lord; *
exceedingly glad shall he be of your salvation.
2  You have given him his heart’s desire, *
and have not denied him the request of his lips.
3  For you shall meet him with the blessings of goodness, *
and shall set a crown of pure gold upon his head.
4  He asked you for life, and you gave it to him: *
length of days, for ever and ever.
5  His honor is great because of your salvation; *
glory and majesty shall you lay upon him.
6  For you shall give him everlasting felicity *
and make him glad with the joy of your countenance.
7  For the King puts his trust in the Lord, *
and because of the mercy of the Most High, he shall not 
be moved.
8  All your enemies shall feel your hand; *
your right hand shall find those who hate you.

9  You shall make them like a fiery oven in the time
  of your wrath; *
the Lord shall destroy them in his displeasure,
and the fire shall consume them.
10  Their offspring you shall root out of the earth, *
and their seed from among the children of men.
11  For they intended evil against you, *
and imagined wicked schemes, which they are not able 
to perform.
12  Therefore you shall put them to flight, *
and the strings of your bow you shall aim at their faces.
13  Be exalted, O Lord, in your own strength; *
so we will sing and praise your power.
