Passage
And early in the morning he came again into the temple, and all the people came unto him; and he sat down, and taught them.
And early in the morning he came again into the temple, and all the people came unto him; and he sat down, and taught them.
John 8:1 Jesus went unto the mount of Olives.
John 8:2 And early in the morning he came again into the temple, and all the people came unto him; and he sat down, and taught them.
John 8:3 And the scribes and Pharisees brought unto him a woman taken in adultery; and when they had set her in the midst,
John 8:4 They say unto him, Master, this woman was taken in adultery, in the very act.
The verse centers on "early", "morning", "came", "again", "temple", "people", and "down". It is saying that the verse draws attention to "early" and "morning", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 1's "Jesus went unto the mount of Olives..." into verse 3's "And the scribes and Pharisees brought unto...", so "early" and "morning" belong inside that flow. In John context, the local focus is the identity of Jesus, new birth, eternal life, and belief and unbelief.
A plain takeaway is to answer the verse's own emphasis on "early" and "morning" with trust shaped by these words, not by a vague optimism outside the passage.
