The Standard Prayer Book by Rev. Simeon Singer is a Jewish Siddur that serves as a comprehensive guide to Jewish prayer and practice. This prayer book includes a collection of prayers, meditations, and sacred texts traditionally recited during daily worship, Shabbat, and Jewish holy days, as well as for life-cycle events such as circumcision, marriage, and funerals. Reverently curated, it features the Ten Commandments, Maimonides' 13 Principles of Faith, and Pirqe Aboth (Ethics of the Fathers), among other essential writings. Singer's work remains a beloved resource for Jewish worship and reflection, preserving ancient traditions while offering guidance for modern spiritual life.
