KJV:
Then I commended mirth, because a man hath no better thing under the sun, than to eat, and to drink, and to be merry: for that shall abide with him of his labour the days of his life, which God giveth him under the sun.
NASB:
So I commended pleasure, for there is nothing good for a man under the sun except to eat and to drink and to be merry, and this will stand by him in his toils throughout the days of his life which God has given him under the sun.
KJV:
Then I beheld all the work of God, that a man cannot find out the work that is done under the sun: because though a man labour to seek it out, yet he shall not find it; yea further; though a wise man think to know it, yet shall he not be able to find it.
NASB:
and I saw every work of God, I concluded that man cannot discover the work which has been done under the sun. Even though man should seek laboriously, he will not discover; and though the wise man should say, "I know," he cannot discover.
KJV:
For all this I considered in my heart even to declare all this, that the righteous, and the wise, and their works, are in the hand of God: no man knoweth either love or hatred by all that is before them.
NASB:
For I have taken all this to my heart and explain it that righteous men, wise men, and their deeds are in the hand of God. Man does not know whether it will be love or hatred; anything awaits him.
KJV:
Go thy way, eat thy bread with joy, and drink thy wine with a merry heart; for God now accepteth thy works.
NASB:
Go then, eat your bread in happiness and drink your wine with a cheerful heart; for God has already approved your works.
KJV:
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.
NASB:
Just as you do not know the path of the wind and how bones are formed in the womb of the pregnant woman, so you do not know the activity of God who makes all things.
KJV:
Rejoice, O young man, in thy youth; and let thy heart cheer thee in the days of thy youth, and walk in the ways of thine heart, and in the sight of thine eyes: but know thou, that for all these things God will bring thee into judgment.
NASB:
Rejoice, young man, during your childhood, and let your heart be pleasant during the days of young manhood. And follow the impulses of your heart and the desires of your eyes. Yet know that God will bring you to judgment for all these things.
KJV:
Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.
NASB:
then the dust will return to the earth as it was, and the spirit will return to God who gave it.
KJV:
Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man.
NASB:
The conclusion, when all has been heard, is: fear God and keep His commandments, because this applies to every person.
