O blessed are those who fear the Lord.

"O blessed are those who fear the Lord" is a gentle, flowing setting of Psalm 128, a scripture passage deeply cherished in Catholic worship for its vision of a faithful, flourishing household. Arranged specifically as a duet for alto voices, the melody carries a warm resonance that perfectly suits the text's promises of fruitful vines and children gathered around the table.

Choirs most often bring this piece out during the Liturgy of the Word at weddings, where its message of domestic blessing and lifelong prosperity serves as a prayer for the newly married couple. It also finds a natural home on the Feast of the Holy Family or during Ordinary Time when the readings turn to themes of trust and obedience.

The 12/8 time signature gives the music a steady, pastoral lilt, allowing the cantors to deliver the verses with clarity and grace. As the congregation joins in the simple, memorable refrain, the psalm becomes a shared declaration of faith, a reminder that true happiness and peace are found in walking the ways of the Lord.
