'Observed' in the Bible

As I observed the living beings, I noticed one wheel on the earth beside each being that is, for the four of them.

As I continued to watch, I observed four wheels beside the cherubim, one wheel beside each cherub. The wheels resembled beryl stone.

All of a sudden, we were at the exterior wall that completely surrounded the Temple. The man whom I had observed held a measuring reed that was six cubits long as measured in cubits that were a cubit and a handbreadth long. As he measured the thickness of the wall, he measured out one reed. Its height was also one reed.

I observed a raised platform that surrounded the Temple, and the foundations of the side chambers were a full six cubits deep.

His appearance in the vision that I was having was similar to what I observed in the vision where he had come to destroy the city, and also like the visions that I saw by the Chebar River. I fell flat on my face

It is to be for use by priests from the descendants of Zadok, who have observed the things with which I charged them and who did not wander astray when the Israelis went astray, just as the descendants of Levi wandered astray.
