9 "The heart is deceitful above all things

And it is *extremely sick;

Who can understand it fully and know its secret motives? [Matt 13:15-17; Mark 7:21-23; Eph 4:20-24]

10 "I, the Lord, search and examine the mind,

I test the heart,

To give to each man according to his ways,

According to the results of his deeds.
