Why do the Jews suddenly tell the healed blind man to “Give God the glory!” (John 9:24)?
They actually weren't telling him to give glory to God for his healing.
“Give God the glory” was an old and common Jewish
oath to tell the truth before God: And Joshua said to Achan, “My son, I beg you, give glory to the LORD,
the God of Israel, and make
confession to Him, and tell me now what you have done; do not hide it from
me” (Joshua 7:19).
So, were the Jews telling the healed blind man to
tell the truth?
“Give God the glory! We know that this Man is a
sinner” amounts to, “Tell the truth! We know that this Man is a sinner.” They were
telling him to agree with
them.
How does the healed blind man respond to the Jews?
He sticks to what he knows and what they cannot refute:
“I do not know whether He is a sinner. I know one
thing, that I was blind; now I see” (John 9:25).
Why do the Jews repeat, “What did He do to you? How
did He open your eyes” (John 9:26)?
They are out of arguments and have nothing else to say. They sound like
they are almost pleading with him to recant how he had been healed.
Does the healed blind man oblige?
See below.
Why did the Jews “revile” (John 9:28) the healed
blind man?
Instead of obliging, he dared to ask if they want to become Jesus'
disciples, which sets off the Jews and gives them an excuse to vent at
him their pent-up frustration and anger.
What do the Jews then do next?
Admit to the healed blind man their ignorance about Jesus' origins:
“We do not know where this One is from” (John
9:29).
