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 whom does a Jew pray?
Can He be described? Does He have a name?
No, there is no description with which to imagine Him, no name with which to grasp Him.
Even the pronoun “Him” implies too much to be true—as though He could be a third party, absent or present. Even the title “Infinite Light” misses the mark, as though He were only light.
But He is not light. He is the source of light. At the source of all light, there is no absence or presence, no being or not being.
There is only “You.” Here, now, known to all beings. And yet beyond the grasp of any knowledge.
It is truly inconceivable, certainly outrageous, but we puny, mortal creatures turn to the heavens and beyond the heavens and say, “You.”
As Rabbi Yosef Yitzchak of Lubavitch wrote:
You, that all know of You.
You, that all put their trust only in You.
You, that all plead only to You.
You, that no creation nor emanation knows who and what You are.
And so we pray to You alone, for You alone, the Unknowable, are known to all.
