Ecclesiastes 11:2-4

²Give a portion to seven, and also to eight; for thou knowest not what evil shall be upon the earth.

³If the clouds be full of rain, they empty themselves upon the earth: and if the tree fall toward the south, or toward the north, in the place where the tree falleth, there it shall be.

⁴He that observeth the wind shall not sow; and he that regardeth the clouds shall not reap.
