# After the suffering of his life

"After the servant has suffered" 

# he will see light

Many versions understand "light" here to stand for life. That is, the servant will become alive again.

# My righteous servant

Here "my" refers to Yahweh.

# he will bear their iniquities

"he will take their punishment" or "he will be punished for their sins." Alternate translation: "he will take their guilt upon himself" or "he will be guilty for their sins"
