XXpen-shun (1 Esdras 4:56, the King James Version "and he commanded to give to all that kept the city pensions and wages"; kleros, "allotted portion," usually (here certainly) of lands (the Revised Version (British and American) "lands")): Literally it means simply "payment," and the King James Version seems to have used the word in order to avoid any specialization of kleros. There is no reference to payment for past services.
