Jeremiah 17:8-10

New Catholic Bible

⁸ They will be like a tree planted by the water
    that spreads out its roots to the stream.
When the heat comes, it does not fear;
    its leaves stay green.
It is not concerned in a year of drought,
    and it never fails to bear fruit.
⁹ The heart is more deceitful than any other thing,
    and it is also perverse.
    Who can uncover its secrets?
¹⁰ I, the Lord, search the heart
    and probe the mind
to reward all according to their conduct
    and as their deeds deserve.
