'Thoughts' in the Bible

And the Lord saw that the sin of man was great on the earth, and that all the thoughts of his heart were evil.

And when the sweet smell came up to the Lord, he said in his heart, I will not again put a curse on the earth because of man, for the thoughts of man's heart are evil from his earliest days; never again will I send destruction on all living things as I have done.

And Abraham answering said, Truly, I who am only dust, have undertaken to put my thoughts before the Lord:

And he said, See now, I have undertaken to put my thoughts before the Lord: what if there are twenty there? And he said, I will have mercy because of the twenty.
