In that latter respect it was used by Johann Sebastian Bach as a cantus firmus in his chorale cantata Herr Gott, dich loben alle wir (BWV 130).
The Genevan Psalter was compiled over a number of years in the Swiss city of Geneva, a center of Protestant activity during the Reformation, in response to the teaching of John Calvin that communal singing of psalms in the vernacular language is a foundational aspect of church life.
The original lyrics set to this tune in the Genevan Psalter are a paraphrase of Psalm 134: Or, in English translation:[4] You faithful servants of the Lord, sing out his praise with one accord, while serving him with all your might and keeping vigil through the night.
Old 100th is commonly used to sing the lyrics that begin "All People That on Earth Do Dwell," Psalm 100, a version that originated in the Anglo-Genevan Psalter (1561) and is attributed to the Scottish clergyman William Kethe.
The first verse is as follows:[6] All people that on earth do dwell, Sing to the Lord with cheerful voice; Him serve with mirth, His praise forth tell; Come ye before Him and rejoice.
A hymn commonly sung to Old 100th is "Praise God, from Whom All Blessings Flow," using the text often referred to as the Doxology, written in 1674 by Thomas Ken, a bishop in the Church of England.
