Who was Cush and what had he done to David? (Psalm 7 title)

Psalm 7 title:
A shiggaion[d] of David, which he sang to the Lord concerning Cush, a Benjamite.
1 Lord my God, I take refuge in you;
    save and deliver me from all who pursue me,
2 or they will tear me apart like a lion
    and rip me to pieces with no one to rescue me.
