“ I have set thee for a tower and a fortress among my people, that thou mayest know and try their way. And I will make thee unto this people a fenced brasen wall: and they shall fight against thee, but they shall not prevail against thee: for I am with thee to save thee and to deliver thee, saith the LORD. For the Lord GOD will help me; therefore shall I not be confounded: therefore have I set my face like a flint, and I know that I shall not be ashamed. ”
