Psalm 100: Enter His Gates With Thanksgiving, and His Courts With Praise

Psalm 100 (Greek numbering: Psalm 99) is part of the biblical Book of Psalms. It may be used as a canticle in the Anglican liturgy of Morning Prayer, when it is referred to by its incipit as the Jubilate or Jubilate Deo. It also constitutes the bulk of the first movement of Leonard Bernstein's Chichester Psalms.

According to Professor William Schniedewind from UCLA, Psalm 100 was also part of the liturgy of the ancient Jerusalem temple and was reused in later Psalms and prophetic texts, particularly the ambiguous verse 3 ("Are We His People or Not? Biblical Interpretation During Crisis," Biblica 76 (1995), pp. 540-550).

In Judaism, Psalm 100 () is part of the daily prayer service, except on Shabbat, festivals, Chol HaMoed of Pesach, and the days before Yom Kippur and Pesach. Psalm 100 is representative of the Thanksgiving offering, which thanks God for having been saved from dangers we face every day. A person always faces danger in his daily routine, even though he may be unaware of it.

Psalm 100 is omitted the day before and during Pesach because the Thanksgiving offering is composed of a loaf of bread, which is chametz that may not be consumed during Pesach. It is omitted the day before Yom Kippur because no food is consumed on Yom Kippur.
