"'And you, son of man, do not be afraid of them or their words. Do not be afraid, though briers and thorns are all around you and you live among scorpions. Do not be afraid of what they say or terrified by them, though they are a rebellious house.'" NIV translation
Three times in this verse God tells the prophet to not be afraid of the rebellious people. Even though he is surrounded by the disobedient, God has assured him that He is in control and so there is no need to fear any man. The same can be said for us as we serve the Lord and face opposition.
"'But you, son of man, listen to what I say to you. Do not rebel like that rebellious house; open your mouth and eat what I give you.'" NIV translation
God continues to tell Ezekiel to be obedient and here is a big test. When God tells him to eat, he must have been thinking "eat what" because he was not around any food. The command did not make any sense to him but God is showing him and us that our obedience has to continue even when our understanding fails us. We have to remember that He knows all things and failing to obey is rebellion against God.
"Then I looked, and I saw a hand stretched out to me. In it was a scroll, which he unrolled before me. On both sides of it were written words of lament and mourning and woe." NIV translation
Now, a hand is extended that contains a scroll which has the Ten Commandments written on it. On the front are the laws concerning man's relationship with God and on the back are the laws concerning man's relationship with their fellow man. These are words of "lament and mourning and woe" because man cannot keep the law perfectly for salvation and so there is no hope in the laws only conviction.
