'Particular' in the Bible

However, in a particular matter may the Lord pardon your servant: When my master, the king of Aram, goes into the temple of Rimmon to worship and I, as his right-hand man, bow in the temple of Rimmon—when I bow in the temple of Rimmon, may the Lord pardon your servant in this matter.”

Later he went to address his master. Elisha asked him, "Where did you go, Gehazi?" "Your servant went nowhere in particular," he said.
