Answer:
I moan I groan I chase after you. I never seem to rest. Timeβs up for you.
I begin and have no end and I end all that begins. What am I?
I have three feet but no arms or legs
You use a knife to slice my head but you weep beside me when I am dead
I am the beginning of the end and the end of time and space. I am essential to creation and I surround every place.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
