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.
To one whose self is his body, death of the body is death of the self. But for one whose self is his love, awe and faith, there is no death, only a passing. From a state of confinement in the body, he makes the passage to liberation. He continues to work within this world, and even more so than before.
The Talmud says that Jacob, our father, never died. Moses, also, never died. Neither did Rabbi Judah the Prince. They were very high souls who were one with Truth in an ultimate bond—and since Truth can never die, neither could they.
Yes, in our eyes we see death. A body is buried in the ground, and we must mourn the loss. But this is only part of the falseness of our world. In the World of Truth, they are still here as before.
And the proof: We are still here. For if these high souls would not be with us in our world, all that we know would cease to exist.
