I have seen the travail which God hath given to the sons of
men
The pains and trouble they are at to get a little wisdom and knowledge, ( Ecclesiastes 1:13 ) ; and so to obtain riches and honour, peace and plenty, which sometimes they do obtain, and sometimes not; and when they do, do not keep them long, for there is a time for everything. This the wise man had observed, in a variety of instances; and he considered the end of God in it, which was for men to be exercised in it,
or "by it"; or "to afflict" or "humble [them] by it" F12; to let them see that all their toil and labour signified little; all depended on a divine blessing, and no happiness was to be had in the creatures; all was vanity and vexation of spirit; (See Gill on Ecclesiastes 1:13).
