Matthew Poole and continuators on Genesis 6:5

5. And God saw that the wickedness of man was great in the Earth, and that every imagination of the thoughts of his heart was only evil continually .

To which the Scripture commonly ascribes all mens actual wickedness, as Psal. 41. 6. Prov. 4. 23. and 6. 14, 18. Ier. 17. 9. Matth. 15. 19. Rom. 3. 10. &c. Thereby leading us from acts of sin to the original corruption of nature as the cause and source of them.

(i. e.) That man was perpetually either doing or contriving wickedness, that not only his actions were vile, but his principles also, his very soul, yea the noblest part of it, which might seem most free from the contagion, his Mind and Thoughts, were corrupt and abominable, and so there was no hopes of amendment.
