The prince of the tribe of Simeon was named Shelumiel, "my God is peace," to indicate that in spite of the sin of Zimri, head of this tribe, through whom four and twenty thousand men among Israel died, God nevertheless made peace with this tribe.
The prince of the tribe of Judah bore the name Nahshon, "wave of the sea," the son of Amminadab, "prince of My people," because the prince received this dignity as a reward for having plunged into the waves of the Red Sea to glorify God's name.
The tribe of Issachar had for its prince Nethanel, "God gave," for this tribe devoted its life to the Torah given by God to Moses. Accordingly Nethanel was called the son of Zuar, "burden," for Issachar assumed the burden of passing judgement on the lawsuits of the other tribes.
