This Chapter in the Liturgy
Exodus 10 is not a standard single-reading fixture in the Roman Rite of the Mass. It appears more commonly in the broader catechetical and scriptural formation of the Church, or within the Liturgy of the Hours and study settings that explore the Exodus narratives. When chosen for liturgical use, it is often within a thematic sequence on God’s deliverance, divine justice, and the prefiguration of Passover, rather than as a regular, recurring Sunday reading.
