Everytime somebody like Enus was mentioned
I would turn green, me, being in the trenches
Him, living adventureous not worrying about expenditures
Hova is refering to Enus Cosby, Bill Cosby’s son. Because of his father’s status, he could get whatever he wanted while Jay was stuck in the ghetto, hustling for survival. Enus was then fatally shot and carjacked while trying to change a flat. This calls back the previous line
Knowin I can go, just switchin' a spare
On the highway of life, nigga it’s sharp in my sight.
