Psalm 23 describes God as his shepherd, in the role of protector and provider. The psalm is read, recited and sung by Jews and Christians. It has been called the best-known of the psalms for its universal theme of trust in God. Like all psalms, Psalm 23 was used in worship by the ancient Hebrews.
For Christians the image of God as a shepherd evokes connections not only with David but with Jesus, described as “Good Shepherd” in the Gospel of John. The phrase about “the valley of the shadow of death” is often taken as an allusion to the eternal life given by Jesus.
