"Proverbs or Promises, Kings and Mothers, and Wrestling with God"

1. I heard you mention on the podcast that a proverb is not a promise. Is that true for every proverb in the book of Proverbs? Is there no proverb that is also a promise?

 2. I've been re-reading 1 and 2 Kings and think I've noticed a trend: when a king does right by the Lord, his mother is named. If he does evil, his mother is not named. Is there a reason/significance for this?  

3. What are we supposed to take away from the story of Jacob wrestling with God in Genesis 32? If he was wrestling with God in human form, would that mean he was wrestling with Jesus?
