Why did He tell him not to fear?
Malbim: He sent him to say harsh words to the nation. Do not fear lest they do evil to you. Even if they say to do evil to you, do not fear. Even though they will refuse to hear and will sting You like a painful thorn, or like a scorpion, do not fear their talk to kill you. Do not lower yourself in front of them. They are "Beis Meri"; they cannot overcome you.
