You can't beat me, kill me
I'll be back in three days disguised as a gardener with my kicks filthy

from Jay Electronica – My World (Nas Salute) Lyrics on Rap Genius

Meaning

Jay, like Jesus, would just arise three days later should an opponent ever defeat him.

He probably uses “filthy” to mean two contradictory things.
1. He will arise with his kicks dirty. What else would you expect? He was dead!
2. He will arise with his kicks shiny and glistenin'. How? He’s the goddamn Messiah!

In the Gospel of John, Mary Magdalene saw Jesus after his resurrection, but mistook him for a gardener.

John 20:13-17

And they say unto her, Woman, why weepest thou? She saith unto them, Because they have taken away my Lord, and I know not where they have laid him. And when she had thus said, she turned herself back, and saw Jesus standing, and knew not that it was Jesus. Jesus saith unto her, Woman, why weepest thou? whom seekest thou? She, supposing him to be the gardener, saith unto him, Sir, if thou have borne him hence, tell me where thou hast laid him, and I will take him away. Jesus saith unto her, Mary. She turned herself, and saith unto him, Rabboni; which is to say, Master. Jesus saith unto her, Touch me not; for I am not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father; and to my God, and your God.
