Psalms 120-134 are called songs of ascent, possibly because Jewish pilgrims sang these songs while traveling up into the Judean hills to celebrate a Jewish holiday in Jerusalem. The subtitle wasn’t part of the original psalm. And the possible byline “of David,” isn’t necessarily a byline. The vague phrase could mean the song was written by David, about David, or was inspired by David. Almost half of the psalms are attributed to David in this way, 73 of 150. Ancient Jewish history tells of David playing a lyre and writing songs. For one, he wrote a song of mourning at the battlefield death of King Saul and his sons: “How have the mighty fallen!” (2 Samuel 1:19-27 New American Standard Bible). An ancient Jewish scroll from about the time of Jesus, discovered among the famous Dead Sea Scrolls, reports that David wrote 3,600 songs.
