Ecclesiastes 11:4

2Give a portion to seven, yes, even to eight; for you don’t know what evil will be on the earth.

3If the clouds are full of rain, they empty themselves on the earth; and if a tree falls toward the south, or toward the north, in the place where the tree falls, there shall it be.

4He who observes the wind won’t sow; and he who regards the clouds won’t reap.

5As you don’t know what is the way of the wind, nor how the bones grow in the womb of her who is with child; even so you don’t know the work of God who does all.

6In the morning sow your seed, and in the evening don’t withhold your hand; for you don’t know which will prosper, whether this or that, or whether they both will be equally good.
