'Thinking' in the Bible

when someone told me, 'Behold, Saul is dead,' thinking to have brought good news, I took hold of him, and killed him in Ziklag, which was the reward I gave him for his news.

The king and his men went to Jerusalem against the Jebusites, the inhabitants of the land, who spoke to David, saying, "Unless you take away the blind and the lame, you shall not come in here;" thinking, "David can't come in here."
