In the 23rd Psalm (Greek numbering: Psalm 22) in the Hebrew Bible/Old Testament, the writer describes God as his Shepherd. The text, beloved by Jews and Christians alike, is often alluded to in popular media and has been set to music many times.
For Christians the image of God as a shepherd evokes connections not only with David but with Jesus, described as "the 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.
Often mentioned within the Deathlands, many situations and locations have been compared to the Valley of the Shadow of Death.
