Ecclesiastes 5:3

5:3 Just as dreams come when there are many cares,

so the rash vow of a fool occurs when there are many words.

Ecclesiastes 5:16

5:16 This is another misfortune:

Just as he came, so will he go.

What did he gain from toiling for the wind?

Ecclesiastes 7:12

7:12 For wisdom provides protection,

just as money provides protection.

But the advantage of knowledge is this:

Wisdom preserves the life of its owner.
