I saw Matisyahu play this live and watched the guitarists hands... I am 100% that this 
is the real chords to this song....

Its literally 4 Barre Chords

    Em       D        A       Bm

e----7-------5--------5---------7------------------------------|
B----8-------7--------5---------7------------------------------|
G----9-------7--------6---------7------------------------------|
D----9-------7--------7---------9------------------------------|
A----7-------5--------7---------9------------------------------|
E----0-------x--------5---------7------------------------------|



At the beginning he picks out the chords nicely like this...

e-----------------------------------------------------------|
B-------8-------------7--------------5------------7---------|
G---------9-------------7--------------6------------7-------|
D----9--------9-----7-------7--------------7------------9---|
A--7--------7-----5-------5-------7------7------9-----9-----|
E-------------------------------5--------------7------------|



The verses he uses upstrokes for that reggae style sound

e----7---7----5---5----5---5----7---7--------------------|
B----8---8----7---7----5---5----7---7--------------------|
G----9---9----7---7----6---6----7---7--------------------|
D----9---9----7---7----7---7----9---9--------------------|
A--------------------------------------------------------|
E--------------------------------------------------------|

The Chorus is played with downstrokes and with different timing
