The little foxes!

(Arthur Pink)

"Catch the foxes for us — the little foxes that are ruining the vineyards!" Song of Songs 2:15

Though there may be nothing in my outward conduct for which the Lord is chastising me — yet it is likely there is something within against which He is intimating His displeasure, and for which He requires me to humble myself.
  A spirit of selfishness,
  the allowing of pride,
  the workings of self-will,
  the stirrings of rebellion when Divine Providence crosses me,
  the exercise of self-righteousness
may be the plague-spots of my soul which need purging.

In the rush and pressure of every-day life, the little foxes that are ruining the vineyards are apt to be neglected; and if we are careless, then we must not be surprised if we are placed on our backs for a season . . .
  that there may be time for reflection and opportunity for closer dealings between the soul and God,
  that the hidden things of darkness may be brought out into the light and faithfully dealt with.

"Search me, O God, and know my heart; test me and know my anxious thoughts. Point out anything in me that offends You, and lead me along the path of everlasting life!" Psalm 139:23-24
