Question 1:
In Proverbs 10:14, why does it say "store up"? Does this mean to save the sharring of it for a time and place worthy of it? For another wise person to receive the telling of? Why in this verse is it "store up" and not something like "pursue"?

Question 2:
In Proverbs 14:10, What does this mean? I am completely lost. Maybe I should go back to it later.

Question 3:
In Proverbs 15:10, Does this mean that it is possible to walk away from your salvation?

Question 4:
In Isaiah 6:2, Why do the seraphim cover their feet and face? Is God so awsome that even an angelic creature cannot bare the sight of God? If so, why do they also cover their feet?

Thanks for any answers you can give me.
