“The Jews answered him, We have a law, and by our law he ought to die, because he made himself the Son of God.”
King James Version (KJV)
19:7 By our law he ought to die, because he made himself the Son of God - Which they understood in the highest sense, and therefore accounted blasphemy.
Joh 19:7 We have a law. Failing in their purpose, they now fall back on their charge of blasphemy: "He made himself the Son of God".
