Tuesday night Tonight, Sunday, was the first night of the Hebrew month of Elul. This month is special in preparation for the Jewish High Holy Days of Rosh Hashanah and Yom Kippur. We search ourselves for our failings, commit to cease them, sincerely apologize to those we've harmed, and create new ways of behavior. The process is called Teshuvah, or return. This doesn't mean we have come all the way or achieved perfection, but rather we have made the sincere and real efforts to come closer to being and acting as we understand G-d desires for us.
When Moses ascended Mount Sinai for forty days to receive the Ten Commandments, G-d's Law, the Hebrews were fearful he wouldn't return and created a Golden Calf to worship and party. When Moses descended, in anger he smashed the tablets. G-d has not decided 'what to do with you,' and requires the Hebrews to abandon their former ways and corruptions of living as slaves in Egypt. G-d instructed Moses to again climb Mount Sinai to receive a replacement. Forty days later, during which time Moses asked of G-d to forgive the Hebrews' sin he was instructed that the Israelites repent of their weakness and faithfully observe certain holy days. Moses returned with the Ten Commandments and G-d's forgiveness.
The first day of Elul is the second time Moses went up on Mount Sinai, and 40-days later, when Moses returns, Yom Kippur, is when our fate is sealed based upon our acts.
It is not our sins toward G-d that most matters but our sins toward each other. A central reading during Yom Kippur is from Isaiah in which it is not our pieties that earn us G-d's favor but how we treat each other, particularly those more in need. Before our sins toward G-d can be forgiven, we must first earnestly strive for the fine balance of G-d's earthly standards of justice and mercy.
As distinct from holy days, like the Sabbath, during Elul we do not cease the work that can distract from our focus on G-d's way, or dress up to enter a sanctuary and pray our devotions as we would in entering the Lord's palace. We continue our mundane activities while our Lord is consciously invited into our fields to see how we daily live, correct and improve ourselves.
