Well we pray a verse of this psalm every time we sit down to the Divine Office, so…
“Deus in adjutorium” (Psalm 69)
 In finem. Psalmus David in rememorationem, quod salvum fecerit eum Dominus.
Unto the end. A psalm of David in remembrance that He saved him, did the Lord.
 Deus, in adjutorium meum intende; Domine, ad adjuvandum me festina.
God, unto my assistance hasten; O Lord, unto aiding me hurry.
 Confundantur, et revereantur, qui quaerunt animam meam.
Let them be dismayed and let them fear, who seek my soul.
 Avertantur retrorsum, et erubescant, qui volunt mihi mala; avertantur statim erubescentes qui dicunt mihi : Euge, euge!
Let them be turned away again and let them be ashamed, who will for me evils; let them be turned away immediately, ashamed, who say to me, “Good! Good!”
 Exsultent et laetentur in te omnes qui quaerunt te; et dicant semper : Magnificetur Dominus, qui diligunt salutare tuum.
Let them exsult and be glad in You, all who seek You; and let them say ever, “May He be made great, the Lord,” those who love Your salvation.
 Ego vero egenus et pauper sum; Deus, adjuva me. Adjutor meus et liberator meus es tu; Domine, ne moreris.
But I, needy and poor am I; O God aid me. My helper and my liberator are You; O Lord lest You delay!
v. 4 euge Apparently I chose “Yes!” to render this back when I did psalm 34. Here I think it can be taken either positively or negatively with neat differences. If it’s the gloating of an enemy over David, then it’s simply parallel to the first half of the verse. David wants God to turn back his enemies. If, on the other hand, it’s genuine well-wishing, then David is asking God to turn back all public opinion, whether good or bad. I think given the whole psalm the former makes the most sense but I like that we can play games with the latter idea as well.
