This selection of Psalm 50, read this morning at Morning Prayer, always stands out to me:

16     But to the wicked God says: *
“Why do you recite my statutes,
and take my covenant upon your lips;
17     Since you refuse discipline, *
and toss my words behind your back?
18     When you see a thief, you make him your friend, *
and you cast in your lot with adulterers.
19     You have loosed your lips for evil, *
and harnessed your tongue to a lie.

20     You are always speaking evil of your brother *
and slandering your own mother’s son.
21     These things you have done, and I kept still, *
and you thought that I am like you.”
