It is a vice we associate with women, discontent. I have told you before that most all, if not everyone, of the difficulties in marriages that I have dealt with in my ministry through the years have been first reported to me by the wife. The man did not come to tell me that his marriage was not what it should be, the woman did. Time after time after time. It is no credit to the husband that this is so, but it is a fact that women are much more actively unhappy and less able to accept their unhappiness in marriage than men are, as a rule.
Women consume the lion's share of drugs for depression.
So far the woman. In the case of the man, in vv. 17-19, he is addressed not in terms of his relationships but in terms of his toil. The hardship and skimpiness of his livelihood is the part of his judgment that God saw fit to mention as standing for all the rest. There are unmarried men and women, women who never have children, and so on.
