The devious heart (Jer 17:9-17:10)

“The heart is devious

Above all things.

The heart is perverse.

Who can understand it?

I!

Yahweh!

I test the mind!

I search the heart!

In order to give to all

According to their ways,

According to the fruit of their doings.”

Yahweh seems to tell Jeremiah that the heart is devious and perverse. Only he can understand the heart, since Yahweh tests it and searches out the hearts of all people. He can tell by the way that they do things. He can see what the fruit of their actions is. Thus he understands what kind of heart they have.
