What do the four glasses of red wine mean at Passover meal?

There is no mention of four glasses of red wine in the Passover meal, but four cups of wine. These four cups are filled throughout the Passover Seder and have symbolic meaning. Here's an explanation of what each cup represents:

First Cup - Kiddush:

- This is the cup of sanctification, representing the beginning of the Seder. It is filled with wine, and participants recite the Kiddush, blessing God and sanctifying the holiday.

Second Cup - Maggid:

- The second cup is poured after telling the story of the Exodus from Egypt. It symbolizes joy and liberation. As part of the retelling, the youngest child present asks four questions about the Passover, highlighting the uniqueness of the night and the importance of remembering the Exodus.

Third Cup - Tzafon:

- The third cup represents redemption. It is drunk after the main meal and marks the conclusion of the retelling of the Exodus. Participants drink it while leaning on the left side, symbolizing freedom from slavery.

Fourth Cup - Hallel:

- The fourth and final cup signifies praise. It is consumed during the conclusion of the Seder, following the recitation of Psalms of praise and gratitude. This cup completes the Seder and symbolizes reaching the end of the storytelling.

Throughout the Passover Seder, drinking the four cups of wine is an essential part of the rituals and symbols that honor the journey from slavery to freedom and the commemoration of the Israelites' liberation from Egypt.
