Jeremiah 17:5-10

Thus says the LORD:

Cursed is the man who trusts in human beings,

   who seeks his strength in flesh,

   whose heart turns away from the LORD.

He is like a barren bush in the desert

   that enjoys no change of season,

But stands in a lava waste,

   a salt and empty earth.

Blessed is the man who trusts in the LORD,

   whose hope is the LORD.

He is like a tree planted beside the waters

   that stretches out its roots to the stream:

It fears not the heat when it comes,

   its leaves stay green;

In the year of drought it shows no distress,

   but still bears fruit.

More tortuous than all else is the human heart,

   beyond remedy; who can understand it?

I, the LORD, alone probe the mind

   and test the heart,

To reward everyone according to his ways,

   according to the merit of his deeds.
