When Hashem tells Moshe to send the men into Israel to tour the land, Hashem says he should send: אִישׁ אֶחָד אִישׁ אֶחָד לְמַטֵּה אֲבֹתָיו תִּשְׁלָחוּ כֹּל נָשִׂיא בָהֶם, “one man each from his father’s tribe shall you send, everyone a leader among them.” Num. 13,2. The Torah uses the word נָשִׂיא for “leader”.
A Rabbi once pointed out an interesting fact. The word נָשִׂיא contains the Hebrew letters: Nun, Shin, Yud, and Aleph. Using some of the letters from this word you can form the word אין, which means “there is not”. You can also select other letters from this word and form the word “יש”, which means “there is”.
Some leaders “have it” and some leaders “do not have it”. That is, some leaders who think they have it and are capable may not have it, and some who do not think they have it may, indeed, really have it.
It is up to the people who choose the leaders to know who is suited for the job and who is not. The results can be drastic if the wrong people are given power.
