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.
Why must you see every downturn as a punishment? Perhaps, on the contrary, it became time for you to receive greater things from Above.
Only that, like a metal spring, you must first become small before you can unleash your power.
Like an olive, you must allow yourself to be crushed to discover your oil.
Like a seed, you must first come down from your tree and lose yourself within the earth so you can sprout and grow into a mighty oak.
Perhaps all these troubles of yours are G-d's way of helping you along that path, helping you become small.
And if so, the remedy is obvious: Make yourself small on your own and relieve Him of the task.
Truth be told, you can do the job much better on your own—far less painfully and with faster results.
