Even my own familiar friend in whom I trusted, who ate my bread, has lifted up his heel against me. But You, O Lord, be merciful to me, and raise me up, that I may repay them. By this I know that You are well pleased with me, because my enemy does not triumph over me. As for me, You uphold me in my integrity, and set me before Your face forever. Blessed be the Lord God of Israel from everlasting to everlasting! Amen and Amen.
-Psalms 41:9-13

Have you ever had a friend who betrayed you? Well, this passage is saying that even if friends fail, God won't. Although they left you, God won't. He will raise you above your troubles and He'll make sure that your enemies won't affect you.
