The Jewish nation mourned for thirty days following the passing of Moses. (During this time, Joshua, the new leader of the Jewish nation, sent scouts to spy on the land of Canaan, see Jewish History for the 5th of Nissan).
On the 7th of Nissan, the first day after the mourning period came to an end, Joshua instructed the Jews to stock up on provisions and prepare themselves to cross the Jordan river and begin the conquest of the Promised Land. This was the first time Joshua addressed the nation, and they unconditionally accepted him as their new leader.
The actual crossing occurred on the 10th of Nissan.
In 1890, Dr. Moshe Wallach emigrated from his native Germany to the Land of Israel. Ten years later, he founded the Shaarei Zedek Hospital, one of Jerusalem’s most prominent hospitals. Dr. Wallach was a strictly observant Jew, and the hospital protocol follows Shabbat and kashrut observance, and provides religious services for both weekdays and holidays.
In 1929, during a journey by boat from Alexandria to Trieste, Dr. Wallach cured Rabbi Yosef Yitzchak Schneersohn when he fell ill with a kidney ailment.

In today's "Nasi" reading (see "Nasi of the Day" in Nissan 1), we read of the gift bought by the nasi of the tribe of Ephraim, Elishama ben Amihud, for the inauguration of the Mishkan.
For a mitzvah is a candle and Torah is light. (Proverbs 6:23)
Every mitzvah shines its particular light into our world. And there will come a time when you will see that light with your eyes.
Except the candles that are lit for Shabbat before sunset. They shine a light you can see right now.
It may seem an ordinary light, just another flame. But there is nothing ordinary about it.
You have ignited the darkness of our world and extracted its secret:
That it too is light.
