Ecclesiastes 11:1-2

Ignorance of the Future Demands Diligence in the Present

11:1 Send your grain overseas,

for after many days you will get a return.

11:2 Divide your merchandise among seven or even eight investments,

for you do not know what calamity may happen on earth.

Ecclesiastes 11:6

11:6 Sow your seed in the morning,

and do not stop working until the evening;

for you do not know which activity will succeed –

whether this one or that one, or whether both will prosper equally.
