Geneva Bible 1599

Then I behelde the whole worke of God, that man cannot finde out ye worke that is wrought vnder the sunne: for the which man laboureth to seeke it, and cannot finde it: yea, and though the wise man thinke to knowe it, he cannot finde it.

Darby Translation

then I saw that all [is] the work of God, [and] that man cannot find out the work that is done under the sun: because however man may labour to seek [it] out, yet doth he not find [it]; and even, if a wise [man] think to know [it], he shall not be able to find [it] out.

Young's Literal Translation

then I considered all the work of God, that man is not able to find out the work that hath been done under the sun, because though man labour to seek, yet he doth not find; and even though the wise man speak of knowing he is not able to find.

Bible in Basic English

Then I saw all the work of God, and that man may not get knowledge of the work which is done under the sun; because, if a man gives hard work to the search he will not get knowledge, and even if the wise man seems to be coming to the end of his search, still he will be without knowledge.
