Douay-Rheims Bible, Psalms Chapter 54

Exaudi, Deus. A prayer of a just man under persecution from the wicked. It agrees to Christ persecuted by the Jєωs, and betrayed by Judas.


1 Unto the end, in verses, understanding for David. 2 Hear, O God, my prayer, and despise not my supplication: 3 Be attentive to me and hear me. I am grieved in my exercise; and am troubled, 4 At the voice of the enemy, and at the tribulation of the sinner. For they have cast iniquities upon me: and in wrath they were troublesome to me. 5 My heart is troubled within me: and the fear of death is fallen upon me.
6 Fear and trembling are come upon me: and darkness hath covered me. 7 And I said: Who will give me wings like a dove, and I will fly and be at rest? 8 Lo, I have gone far off flying away; and I abode in the wilderness. 9 I waited for him that hath saved me from pusillanimity of spirit, and a storm. 10 Cast down, O Lord, and divide their tongues; for I have seen iniquity and contradiction in the city.
11 Day and night shall iniquity surround it upon its walls: and in the midst thereof are labour, 12 And injustice. And usury and deceit have not departed from its streets. 13 For if my enemy had reviled me, I would verily have borne with it. And if he that hated me had spoken great things against me, I would perhaps have hidden myself from him. 14 But thou a man of one mind, my guide, and my familiar, 15 Who didst take sweetmeats together with me: in the house of God we walked with consent.
16 Let death come upon them, and let them go down alive into hell. For there is wickedness in their dwellings: in the midst of them. 17 But I have cried to God: and the Lord will save me. 18 Evening and morning, and at noon I will speak and declare: and he shall hear my voice. 19 He shall redeem my soul in peace from them that draw near to me: for among many they were with me. 20 God shall hear, and the Eternal shall humble them. For there is no change with them, and they have not feared God:

[16] "Let death": This, and such like imprecations which occur in the psalms, are delivered prophetically; that is, by way of foretelling the punishments which shall fall upon the wicked from divine justice, and approving the righteous ways of God: but not by way of ill will, or uncharitable curses, which the law of God disallows.
[19] "Among many": That is, they that drew near to attack me were many in company all combined to fight against me.

21 He hath stretched forth his hand to repay. They have defiled his covenant, 22 They are divided by the wrath Of his countenance, and his heart hath drawn near. His words are smoother than oil, and the same are darts. 23 Cast thy care upon the Lord, and he shall sustain thee: he shall not suffer the just to waver for ever. 24 But thou, O God, shalt bring them down into the pit of destruction. Bloody and deceitful men shall not live out half their days; but I will trust in thee, O Lord.

"Should we want God to shorten the test and for the end to come soon or should we pray he averts his anger?"

Perhaps a bit of both?

"Have any saints prayed for God to punish mankind or were they like appeasing Him like Moses?"

Well, here's a Psalm:
