Psalm 27

Psalm 27 is the 27th Psalm from the Book of Psalms.

The Psalm is a cry for and ultimately a declaration of belief in the greatness of God and trust in the protection he provides. It may be a sequel of the preceding psalm.

According to some modern scholars, Psalm 27 is a composite work by at least two authors brought together by an editor.

Tradition attributes Psalm 27 to King David.Protestant Christians have traditionally thought of it as written early in David's life, during his flight from King Saul, with Spurgeon suggesting the incident with Doeg the Edomite specifically.Jewish scholars, however, put it toward the end of his life.

Catholic doctrine has traditionally seen the Psalm in two sections. The first section declaring the power of God and a boundless hope that God will bring rescue, and protection from all enemies. The second portion has a clear shift in tone with declaration “I believe". Some scholarship contends it may have originally been two separate Psalms.

In Hebrew the first three verses increase numerically: Two parallel phrases of five words each, then six, then seven, (hinting at completion in Jewish numerology).

In the Roman Rite liturgy, this Psalm is recited, divided into its two parts, at Vespers on Wednesday of the first week of the four-week cycle, as well as being used often as a responsorial psalm at Mass.

This psalm was traditionally performed at monasteries during Sunday Matins office after reading, according to the Rule of St. Benedict set to 530 which attributed the Psalms 21 (20) 109 (108) matins, in order numérique
