'Whether' in the Bible

And who knows whether he will be a wise man or a fool? Yet he will take over all my work that I labored at skillfully under the sun. This too is futile.

The sleep of the worker is sweet, whether he eats little or much, but the abundance of the rich permits him no sleep.

Indeed, I took all this to heart and explained it all: the righteous, the wise, and their works are in God’s hands.People don’t know whether to expect love or hate. Everything lies ahead of them.

If the clouds are full, they will pour out rain on the earth;whether a tree falls to the south or the north,the place where the tree falls, there it will lie.

In the morning sow your seed,and at evening do not let your hand rest,because you don’t know which will succeed,whether one or the other,or if both of them will be equally good.

For God will bring every act to judgment, including every hidden thing, whether good or evil.
