'Thinking' in the Bible

when one told me, saying, Behold, Saul is dead, thinking to have brought good tidings, I took hold of him, and slew him in Ziklag, which was the reward I gave him for his tidings.

And the king and his men went to Jerusalem against the Jebusites, the inhabitants of the land, who spake unto David, saying, Except thou take away the blind and the lame, thou shalt not come in hither; thinking, David cannot come in hither.
