Save me, O God,
 for the waters are come in, even unto my soul.
I stick fast in the deep mire, where no ground is;
 I am come into deep waters, so that the floods run over me.

And why? for thy sake have I suffered reproof;
 shame hath covered my face.
I am become a stranger unto my brethren,
 even an alien unto my mother’s children.
For the zeal of thine house hath even eaten me
 and the rebukes of them that rebuked thee are fallen upon me.

(Coverdale)

The first two verses are not included in today's Mass reading. I just like them. This is one of the imprecatory psalms, full of curses for the psalmist's enemies, and God's. Verse 23 has some relevance for our society.

Let their table be made a snare to take themselves withal 
 and let the things that should have been for their wealth be unto them an occasion of falling.
