παρατηρήσεως, [1 verse]( noun sg fem gen) "Observation" is paratērēsis, which means "observation", "surveillance " "observation" of rules, "close observation" to detect faults, "remark", and "note". -- The Greek noun means "observation" in many senses from  "surveillance" to "scrupulous observation of rules" to a spoken obervation as a "remark". The word means literally "watching over" or "guarding over". This is a classic play on words, critical of the Pharisees for their punctilious observation of Judean law and criticism of other people. Our word "scrutiny" captures the idea best.
