From Wikipedia
“Old 100th” or “Old Hundredth” (also commonly called “Old Hundred”) is a hymn tune in Long Metre from Pseaumes Octante Trois de David (1551) (the second edition of the Genevan Psalter) and is one of the best known melodies in all Christian musical traditions. The tune is usually attributed to the French composer Louis Bourgeois (c. 1510 – c.1560).

Although the tune was first associated with Psalm 134 in the Genevan Psalter, the melody receives its current name from an association with the 100th Psalm, in a translation by William Kethe entitled “All People that on Earth do Dwell.” The melody is commonly sung with diverse other lyrics as well.

All People That on Earth Do Dwell

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.

Know that the Lord is God indeed;
Without our aid He did us make.
We are His folk, He doth us feed,
And for His sheep He doth us take.

Oh, enter then His gates with praise;
Approach with joy His courts unto;
Praise, laud, and bless His name always,
For it is seemly so to do.

For why? The Lord our God is good:
His mercy is forever sure;
His truth at all times firmly stood
And shall from age to age endure.

To Father, Son, and Holy Ghost,
The God whom heaven and earth adore,
From us and from the angel host
Be praise and glory evermore.

We give you thanks and praise, O LORD God, for creating us and giving us life, for redeeming us through the holy life and innocent sufferings and death of Your Son Jesus Christ, and for bringing us to faith in our crucified and risen Savior through Your Word and Sacraments. Graciously keep us in the true faith unto life everlasting. Amen.
