Psalms 41:13

Yea, mine own familiar friend, in whom I trusted, which did eat of my bread, hath lifted up his heel against me.

But thou, O LORD, be merciful unto me, and raise me up, that I may requite them.

By this I know that thou favourest me, because mine enemy doth not triumph over me.

And as for me, thou upholdest me in mine integrity, and settest me before thy face for ever.
