'Observe' in the Bible

Jesus answered them, "Go and tell John what you hear and observe:

They don't eat anything from the marketplace unless they dip it in water. They also observe many other traditions, such as the proper washing of washing cups, jars, brass pots, and dinner tables.)

You say, don't you, "In four more months the harvest will begin?' Look, I tell you, open your eyes and observe that the fields are ready for harvesting now!

Then Jesus said, "Leave her alone so she can observe the day of my burial,

But they have been told about you that you teach all the Jews living among the gentiles to forsake the Law of Moses, and that you tell them not to circumcise their children or observe the customs.

For circumcision is valuable if you observe the Law, but if you break the Law, your having been circumcised has no more value than if you were uncircumcised.

But if we hope for what we do not yet observe, we eagerly wait for it with patience.

You observe that a person is justified through actions and not through faith alone.
