Your email contains great few questions; thanks for sending me.
1. keeping Shabbat for Noahide.
Twice God demands us to observe the Shabbat. Every time there is a difference in the exact command:
A. In exodus 20 (verses 8 - 11), God asks us toremember Shabbat (in a positive way).
The reason is: "For [in] six days the Lord made the heaven and the earth, the sea and all that is in them, and He rested on the seventh day. Therefore, the Lord blessed the Sabbath day and sanctified it."
It's related to all humankind.
B. In Deuteronomy 5 (verses 12 - 15), God asks us to keep the Shabbat (in a passive way - not to do some actions).
The reason is different from Exodus: "And you shall remember that you were a slave in the land of Egypt and that the Lord your God took you out from there with a strong hand and with an outstretched arm; therefore, the Lord, your God, commanded you to observe the Sabbath day."
It's related to the Hebrews nationally only, who were redeemed from Egypt.
This brings an exciting debate between the Hebrew sages and how to read Maimonides.
We hold that Noahide has permission to keep full Shabbat. On the other side, we do not recommend this behavior at all. Think about someone who lives in a place without any Hebrew people. Would he be able to keep Shabbat properly? Not!
What yes? Light candles on Friday nightto rememberthat God created our world in six days, and here he stopped. Do a nice meal with your family without electronic devices, and learn from the Hebrew Bible.Those things mentionremembering Shabbat as a holy day.
2. What Rabbi to follow?
This is a huge question, and it's not the right thing to 'jump' to the Rabbi who is more convenient for a specific question.
In the Cain and Abel narrative, Rabbi Yochanan's interpretation highlights the risks of showing kindness to the wicked, underscoring the need for discernment in acts of compassion. This story prompts us to reflect on moral behavior, emphasizing the importance of considering the character and intentions of those to whom we extend kindness. What broader ethical lessons can we draw from this cautionary tale, and how can we apply them to our interactions with others?
"Israel recently experienced an unfounded terrorist attack, deliberately targeting civilians, encompassing women, children, and the elderly. In the face of adversity, the Jewish people demonstrated their unity and strength, guided by their faith in one God. They aspire to create a world characterized by peace, harmony, and dignity. To contribute, you can help disseminate this message in your language, among your friends, and provide financial support. May blessings be sent to Israel and all those who stand in solidarity. Let us pray for peace, invoking the hope that 'He who makes peace in His heavens, may He make peace upon the people of Israel and the entire world.'"
