KJV: {A Song of degrees for Solomon.} Except the LORD build the house, they labour in vain that build it: except the LORD keep the city, the watchman waketh but in vain.
NASB: A Song of Ascents, of Solomon. Unless the LORD builds the house, They labor in vain who build it; Unless the LORD guards the city, The watchman keeps awake in vain.
KJV: And who knoweth whether he shall be a wise man or a fool? yet shall he have rule over all my labour wherein I have laboured, and wherein I have shewed myself wise under the sun. This is also vanity.
NASB: And who knows whether he will be a wise man or a fool? Yet he will have control over all the fruit of my labor for which I have labored by acting wisely under the sun. This too is vanity.
KJV: For there is a man whose labour is in wisdom, and in knowledge, and in equity; yet to a man that hath not laboured therein shall he leave it for his portion. This also is vanity and a great evil.
NASB: When there is a man who has labored with wisdom, knowledge and skill, then he gives his legacy to one who has not labored with them. This too is vanity and a great evil.
KJV: Behold that which I have seen: it is good and comely for one to eat and to drink, and to enjoy the good of all his labour that he taketh under the sun all the days of his life, which God giveth him: for it is his portion.
NASB: Here is what I have seen to be good and fitting: to eat, to drink and enjoy oneself in all one's labor in which he toils under the sun during the few years of his life which God has given him; for this is his reward.
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.
