'Child' in the Bible

There is one alone, and there is not a second; yea, he hath neither child nor brother: yet is there no end of all his labour; neither is his eye satisfied with riches; neither saith he, For whom do I labour, and bereave my soul of good? This is also vanity, yea, it is a sore travail.

Better is a poor and a wise child than an old and foolish king, who will no more be admonished.

I considered all the living which walk under the sun, with the second child that shall stand up in his stead.

Woe to thee, O land, when thy king is a child, and thy princes eat in the morning!

As thou knowest not what is the way of the spirit, nor how the bones do grow in the womb of her that is with child: even so thou knowest not the works of God who maketh all.
