The heart is…

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? Jeremiah 17:7‭-‬9 KJV https://bible.com/bible/1/jer.17.7-9.KJV
