JMNT(i)
2 Within the midst of her broad place (plaza; square; street), and on each side of the river, [is] a tree (a wood; timber; a log; same word used in Gen. 2:9, LXX; figure for “the cross” in the NT) of life periodically producing twelve fruits, continually yielding (or: giving away) according to each month, and the leaves of the tree (wood; timber) [are given] for (or: into) service (nurture, care; healing or medical service; a body of household attendants) of the multitudes (nations; Gentiles; non-Jews; ethnic groups).
3 And every curse will no longer exist. And God's throne – even the Little Lamb's – will continue being (or: existing) within Her [i.e., the City], and His slaves will continue rendering sacred service to Him,
4 and will constantly see His face, and His Name [is; or: will be] upon their foreheads.
5 And night will no longer continue existing. And so they continuously have no need of the light of a lamp, or even the light of the sun, because [the] Lord [= Yahweh] God will continue giving light upon (or: will constantly illuminate) them, and they will continue reigning (performing as kings) on into the ages of the ages (or: the indefinite time periods of the eons).
