Matthew Poole and continuators on Isaiah 50:7

7 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.

Or rather, But, as this particle is oft rendred. For Gods favour is here opposed to the injuries of Men.

Though as a man I am weak & inconsiderable, yet God will strengthen me to go through my great and hard work.

Therefore I assure my self of success in my employment, and of victory over all mine Enemies.

I have hardened my self with resolution and courage against all opposition. So this or the like Phrase is used, Ezek. 3. 8, 9. which elsewhere signifies obstinacy and impudence▪ as Ier. 5. 3. Zech. 7. 12. so that it notes any settled and unmoveable purpose, whether good or evil.
