If I have sinned, what have I done to you, you who watch over us all? Why have you made me your target? Have I become a burden to you?
NIV
If I have sinned, what [harm] have I done You, O You Watcher and Keeper of men? Why have You set me as a mark for You, so that I am a burden to myself [and You]?
AMP
I have sinned; what shall I do unto thee, O thou preserver of men? why hast thou set me as a mark against thee, so that I am a burden to myself?
