18 “As for those who grieve because they cannot attend the festivals—I took them away from you; they became tribute and were a source of shame to you.
Darby
18 I will gather them that sorrow for the solemn assemblies, who were of thee: the reproach of it was a burden [unto them].
KJV
18 I will gather [them that are] sorrowful for the solemn assembly, [who] are of thee, [to whom] the reproach of it [was] a burden.
