In the Jewish tradition, the “Passover Psalms” were sung during and after the meal. These were Psalms 113-118. Typically, Psalms 113-114 were sung during the meal and Psalms 115-118 were sung at the close of the meal. In Greek, the word “hymn” isn’t limited to the singular, which makes it likely that Jesus and his disciples followed tradition and together sang Psalms 115-118. I would highly encourage you to read through all of these Psalms this week as you reflect on the passion of Jesus in preparation for Good Friday.
