'Thought' in the Bible

“Then you answered and said to me, ‘We have sinned against the Lord. We will go up and fight, just as the Lord our God has commanded us.’ So you equipped every man with weapons of war, and regarded it as easy to go up into the hill country.

It will be [considered] righteousness for us [that is, right standing with God] if we are careful to observe all this commandment before the Lord our God—just as He has commanded us.

Beware that there is no wicked thought in your heart, saying, ‘The seventh year, the year of release (remission, pardon), is approaching,’ and your eye is hostile (unsympathetic) toward your poor brother, and you give him nothing [since he would not have to repay you]; for he may cry out to the Lord against you, and it will become a sin for you.
