Psalm 133:1-3

A Song of the Ascents. Of David. 133  Look! How good and how pleasant it isFor brothers to dwell together in unity!+   It is like the good oil upon the head,+That is running down* upon the beard,Aaron’s beard,+That is running down to the collar* of his garments.+   It is like the dew+ of Herʹmon+That is descending upon the mountains of Zion.+For there Jehovah commanded the blessing [to be],+[Even] life to time indefinite.+
