Hashem instructed Moshe to gather 70 men to help lead the Jewish people. Each of the 12 tribes sent the same number of applicants for the job. (Bamidbar 11:16) Since 70 is not divisible by 12 there were slightly more applicants provided then there were positions. (Rashi to Bamidbar 11:26) How many applicants did each tribe send?
70 / 12 = 5 (with remainder of 10)
Therefore, each tribe sent one more than 5 (i.e. each tribe sent 6 applicants)
