4:16 [There is] no {l} end of all the people, [even] of all that have been before them: they also that come after shall not rejoice in him. Surely this also [is] vanity and vexation of spirit.
(l) They never cease by all means to creep into favour, but when they do not obtain their greedy desires they think themselves abused, as others have been in times past, and so care no more for him.
4:16 No end - This humour of the common people hath no end, but passes from one generation to another. Before them - Before the present generation. And so here are three generations of people noted, the authors of the present change, and their parents, and their children; and all are observed to have the same inclinations. In him - They shall be as weary of the successor, though a wise and worthy prince, as their parents were of his foolish predecessor.
4:13-16 People are never long easy and satisfied; they are fond of changes. This is no new thing. Princes see themselves slighted by those they have studied to oblige; this is vanity and vexation of spirit. But the willing servants of the Lord Jesus, our King, rejoice in him alone, and they will love Him more and more to all eternity.
