Cast your bread upon the waters

Ecclesiastes11: 1 Cast thy bread upon the waters:
for thou shalt find it after many days.
2 Give a portion to seven, and also to eight;
for thou knowest not what evil shall be upon the earth.
3 If 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.
