Ecclesiastes 11:5

2 Give a portion to seven, and even to eight, For thou knowest not what evil is on the earth.

3 If the thick clouds are full of rain, On the earth they empty [themselves]; And if a tree doth fall in the south or to the north, The place where the tree falleth, there it is.

4 Whoso is observing the wind soweth not, And whoso is looking on the thick clouds reapeth not.

5 As thou knowest not what [is] the way of the spirit, How -- bones in the womb of the full one, So thou knowest not the work of God who maketh the whole.

6 In the morning sow thy seed, And at even withdraw not thy hand, For thou knowest not which is right, this or that, Or whether both of them alike [are] good.

7 Sweet also [is] the light, And good for the eyes to see the sun.

8 But, if man liveth many years, In all of them let him rejoice, And remember the days of darkness, For they are many! all that is coming [is] vanity.
