I will gather them that are sorrowful for the solemn assembly, who are of thee, to whom the reproach of it was a burden.
I will gather them that are sorrowful for the solemn assembly - pining after the solemn assembly which they cannot celebrate in exile (Lamentations 1:4; Lamentations 2:6). They who would not "gather themselves" to it when they could (Zephaniah 2:1), could not when they would. But hereafter they shall have both the will and the power.
Who are of thee - i:e., who are of thy true citizens; and whom therefore I will restore.
To whom the reproach of it was a burden - i:e., to whom thy reproach ("the reproach of my people," Micah 6:16, their ignominious captivity) was a burden. "Of it" (Hebrew) is put for of thee, as the person is often changed. Those who shared in the burden of reproach which fell on my people. Compare Isaiah 25:8, "The rebuke of His people shall He take away from off all the earth."
