When visitors first enter the sanctuary of Congregation Shearith Israel in New York City, they often gasp in awe and amazement at the sheer beauty and dignity of this sacred space. It is grand without being overly ornate; it is graceful, understated and powerful.

Years ago, I led a tour of visitors to the synagogue. Upon entering the sanctuary, almost all of our guests reacted as almost everyone does: what a beautiful synagogue! As our forefather Jacob said in a different context: How awesome is this place, this is nothing else but the house of the Lord, and this is the gate of heaven!

“Not with you alone do I make this covenant and this oath; but with those who stand here with us this day before the Lord our God, and also with those who are not here with us this day” (Devarim 29:13-14).

As Moses approached the end of his life, he gathered all the people and affirmed the special covenant between God and Israel. He wanted everyone to understand that this covenant transcended time. It did not relate only to the generation then alive, but to all generations “who are not here with us this day.”

The tragic sinking of a South Korean ship, killing so many passengers, has caught the world’s attention in recent weeks. One of the most disgusting images from this debacle was the photograph of the ship’s captain…who abandoned ship early in the disaster, saving his own life and leaving the passengers to fend for themselves and to die.

Captains are not supposed to abandon ship. When they assume leadership, they are expected to put the lives of their passengers ahead of their own lives.

After their glorious victory and rededication of the Temple, the Hasmoneans established the holiday of Hanukkah to be celebrated by Jews for all future generations. The festival of lights is an occasion for thanksgiving to God, celebration of Jewish pride, remembrance of the importance of religious freedom.

It wasn't too long, though, before this great spiritual and military victory lost its luster. The Hasmoneans--a priestly family--set themselves up as kings. Once they centralized so much power in themselves, corruption soon set in. Their "kings" became ruthless despots; the high priesthood became a political prize going to the highest bidder.

The Torah informs us that Aaron the High Priest lit the Menorah exactly in accord with God’s command (Bemidbar 8:3). Our commentators wonder: why would the Torah need to state that Aaron followed the instructions? We would surely have expected him to heed God’s command!

Rashi notes that Aaron is being praised for not having deviated from the rules. Although he may have had an inclination to be innovative or creative in his assignment, his virtue was that he fulfilled his task exactly to specification.

Ramban suggests that Aaron fulfilled this mitzvah himself, rather than assigning it to his sons who also were eligible to do the lighting. Aaron felt a personal joy and satisfaction in his performance of the kindling of the Menorah in fulfillment of God’s command.

Standing on a mountain and gazing down at the Israelite camp from a distance, Bil’am offers magnificent words of blessing and praise. “None has beheld iniquity in Jacob, neither has one seen perverseness in Israel; the Lord his God is with Him…(Bemidbar23:21) How goodly are your tents, O Jacob, your dwellings, O Israel (24:5).” Bil’am had come to curse the Israelites, but ended up blessing them for their virtues.

After informing us of Bil’am’s lofty praises of Israel, the Torah provides a close up view of the Israelite camp: “…and the people began to commit harlotry with the daughters of Moab. And they called the people unto the sacrifices of their gods; and the people did eat, and bow down to their gods…and the anger of the Lord was kindled against Israel (25:1-3).”

Nadav and Avihu, sons of Aaron the High Priest, offered a “strange fire” on the altar, an offering that had not been commanded by the Lord. As a consequence of this sin, a fire consumed them. This terrible tragedy occurred during the ceremonies dedicating the Mishkan (sanctuary).

What was the nature of the transgression of Nadav and Avihu? Why was their offering of a “strange fire” so serious as to merit the death penalty?

A Judeo-Spanish proverb advises: Va ande te llaman y no ande te queren. Go where you are invited, not where you are (or think you are) wanted. Wait for a formal invitation; do not assume that you are welcome unless you are invited. If one shows up without having been invited, this creates an unpleasant social situation that is embarrassing to host and guest alike.

This proverb reflects a sense of propriety and respectfulness. A person should not impose him/herself on others. Likewise, a person who wants someone present should take the trouble to actually invite him/her. Just as one should not assume he/she is invited, so the host should not assume that the person will attend without an invitation.

In writing about the sin of Nadav and Avihu which led to their tragic deaths, Rabbi Daniel Bouskila of the Sephardic Education Center offered these comments:
