Be not afraid of their faces; their fierce looks, Ezekiel 3:9, the indication of their enraged minds, Daniel 3:19; neither when thou deliverest my message to them, nor when thou mayst be cited before them, Matthew 10:18,19. This is God's answer to Jeremiah's fears in respect of the persons he was to deal with, as the other was in respect of his own consciousness of insufficiency; and he mentions their faces, because the majestic countenance of princes and magistrates is apt to strike a great awe and terror upon children. I am with thee; I will not only send thee as other kings do their ambassadors, but I will go with thee. This God promises to Moses, Exodus 3:12 Deuteronomy 31:6,8. To deliver thee: here God promises his protection for encouragement.
