KJV: I said in mine heart concerning the estate of the sons of men, that God might manifest them, and that they might see that they themselves are beasts.
NASB: I said to myself concerning the sons of men, "God has surely tested them in order for them to see that they are but beasts."
KJV: For that which befalleth the sons of men befalleth beasts; even one thing befalleth them: as the one dieth, so dieth the other; yea, they have all one breath; so that a man hath no preeminence above a beast: for all is vanity.
NASB: For the fate of the sons of men and the fate of beasts is the same. As one dies so dies the other; indeed, they all have the same breath and there is no advantage for man over beast, for all is vanity.
