'Observing' in the Bible

Now John’s disciples and the Pharisees were fasting [as a ritual]; and they came and asked Jesus, “Why are John’s disciples and the disciples of the Pharisees fasting, but Your disciples are not doing so?”

(For the Pharisees and all the Jews do not eat unless they carefully wash their hands, thus observing the traditions of the elders;

Jesus entered Jerusalem and went to the temple [enclosure]; and after looking around at everything, He left for Bethany with the twelve [disciples], because it was already late [in the day].

And He sat down opposite the treasury, and began observing how the people were putting money into the treasury; and many rich people were putting in large sums.

And there were also women observing from a distance, among whom [were] Mary Magdalene, and Mary the mother of James the younger and Joses, and Salome,

Mary Magdalene and Mary the mother of Joses were [carefully] watching to see where He was laid.
