'Second' in the Bible

There is one that is alone, and he hath not a second; yea, he hath neither son nor brother; yet is there no end of all his labor, neither are his eyes satisfied with riches. For whom then,'saith he , do I labor, and deprive my soul of good? This also is vanity, yea, it is a sore travail.

I saw all the living that walk under the sun, that they were with the youth, the second, that stood up in his stead.
