How is God a shield? (Psalm 84:11, NIV)

10 Better is one day in your courts
    than a thousand elsewhere;
I would rather be a doorkeeper in the house of my God
    than dwell in the tents of the wicked.
11 For the Lord God is a sun and shield;
    the Lord bestows favor and honor;
no good thing does he withhold
    from those whose walk is blameless.
