Jeremiah 17 - KJV

Blessed is the man that trusteth in the Lord,
and whose hope the Lord is.
For he shall be as a tree planted by the waters,
and that spreadeth out her roots by the river,
and shall not see when heat cometh,
but her leaf shall be green;
and shall not be careful in the year of drought,
neither shall cease from yielding fruit.

The heart is deceitful above all things, and desperately wicked: who can know it? I the Lord search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings.
