The line here is taken from the famous work of Milton that talks about a divine recompense in that there is a satisfaction of desires from the stand point of the divine power.
When the human works according to the divine will they are entitled to a divine recompense is what the suggestion here is and that the recompense here thus means that their wishes and needs are to be satisfied.
the recompense is in the sense of what is owed to the people.
