'Saith' in the Bible

Vanity of vanities, saith the Preacher; vanity of vanities, all is vanity.

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.

Behold, this have I found, saith the Preacher, laying one thing to another, to find out the account;

Yea also, when the fool walketh by the way, his understanding faileth him, and he saith to every one that he is a fool.

Vanity of vanities, saith the Preacher; all is vanity.
