Okay, trying to think. Totally couldn't concentrate on the previous psalm.
Let's see: I guess the Psalmist is saying that unity is like an ointment, a prophetic ointment. It flows to the entire body and congregation of Christ. It heals and brings a blessing to God's people. Faith works through love. One day Christians will live this, I think. Now we're so divided by race, class, status, education, wealth.
Psalm 1331Behold, how good and how pleasant it is for brethren to dwell together in unity!
2It is like the precious ointment upon the head, that ran down upon the beard, even Aaron's beard: that went down to the skirts of his garments;
3As the dew of Hermon, and as the dew that descended upon the mountains of Zion: for there the LORD commanded the blessing, even life for evermore.
