'Child' in the Bible

There was a certain man—without a dependent, having neither a child nor a brother, yet there was no end to all his labor. Indeed, his eyes were not satisfied with riches and he never asked, “For whom do I labor and deprive myself of pleasure?” This too is vanity (a wisp of smoke, self-conceit); yes, it is a painful effort and an unhappy task.

For when those riches are lost in bad investments and he becomes the father of a son, then there is nothing in his hand [for the support of the child].

It has not seen the sun nor had any knowledge; yet it has more rest and is better off than he.

Woe to you, O land, when your king is a child and when your [incompetent] officials and princes feast in the morning.
