The text based on Psalm 85 and written by an unknown author. The tune is short and sweet, short enough where the seven verses of text won't feel like a marathon. The tune is one of those rarities that end in the V chord, and the last note of the melody is the fifth of that V chord (for those not so well versed in music theory, the tune is in the key of D, but it ends in the A chord, and the melody ends with an E note). This kind of ending also takes place in a little-known tune by the late C. Alexander Peloquin, titled "Creative Love". If you have a Worship II hymnal handy, it's at #257, with the Fred Kaan hymn text, Surrounded by a World of Need.
This tune, like the one I wrote for O that I Could for Ever Dwell, is based on a Gregorian melody from the Liber Usualis, in this case, the Offertory Benedixisti, Domine from III Advent.
(UPDATE VI-28-23: Now part of the partially-completed Christus Vincit Gradual.
