Psalm 127:1 except the Lord keep the city watchman wakes but in vain

John 2:23-25 He knew all man

John 2:23 Now when He was in Jerusalem at the Passover, during the feast, many believed into His name when they saw the signs which He did.

24 But Jesus Himself did not entrust Himself to them, for He knew all men,

25 And because He did not need anyone to testify concerning man. He Himself knew what was in man.

We read above verses many many times,  but not much utterance:
He knows what inside of man,  and he does not trust Himself to man.

This time reading again with new ones, I remembered that He also told people that when Abraham saw Him in John 8:

John 8:56 Your father Abraham exulted that he would see My day, and he saw it and rejoiced.

So if you link these verses together,  you see Jesus is Jehova,  he went through the entire human history,  from Adam,
history of Israel,   from Abraham,  Issac, Jacob,. Exodus, .. Numbers, ...

For sure He knows what is in man. Our natural man can never be trusted,  outward miracles God had done to children of Israel daily,  but they still full of complaints,  unbelieves,.. etc. Eventually all died in the wilderness,  only two made to the good land. So our old man has to die,  and if we grow in divine life, our new man will enter into the good land.
