Who was the first single man to be exiled in the Bible?

Genesis 4:9-12New King James Version (NKJV)

9 Then the Lord said to Cain, "Where is Abel your brother?"

He said, "I do not know. Am I my brother's keeper?"

10 And He said, "What have you done? The voice of your brother's blood cries out to Me from the ground. 11 So now youare cursed from the earth, which has opened its mouth to receive your brother's blood from your hand. 12 When you till the ground, it shall no longer yield its strength to you. A fugitive and a vagabond you shall be on the earth."
