arba kosot n. Hebrew (ar-BAH co-SOTE) Literally, “four cups.” It is traditional to drink four cups of wine during the seder on Pesach. The four cups of wine mirror the four ways that God delivered the Israelites from slavery in Egypt, as written in Exodus 6:6-7: “I will free you from the labors of the Egyptians and [I will] deliver you from their bondage. I will redeem you with an outstretched arm… And I will take you to be My people, and I will be your God.”
