The term "psalm" refers to a sacred song, often in the form of a poem that was written to be sung.
* The Old Testament book of Psalms has a collection of these songs written by King David and other Israelites such as Moses, Solomon, and Asaph, among others.
* The psalms were used by the nation of Israel in their worship of God.
* Psalms can be used to express joy, faith, and reverence, as well as pain and sorrow.
* In the New Testament, Christians are instructed to sing psalms to God as a way of worshiping him.
