A written prayer that Barack Obama left this week in the cracks of the Western Wall, Judaism's holiest site, asks God to guide him and guard his family, an Israeli newspaper reported today. "Lord -- Protect my family and me," reads the note published in the Maariv daily. "Forgive me my sins, and help me guard against pride and despair. Give me the wisdom to do what is right and just. And make me an instrument of your will."
