The Jews therefore murmured concerning him. Perhaps in John 7:32 γογγύζειν means simply "whisper;" but throughout the New Testament (1 Corinthians 10:10; Luke 5:30, with πρός; Matthew 20:11, with κατὰ; cf.
Acts 6:1; Philippians 2:14; 1 Peter 4:9; Wis. 1:10) it has the malevolent meaning conveyed in the LXX. It is used to denote very rebellious feelings against God (Exodus 16:7-9; Numbers 11:1; Numbers 14:27).
The Attic writers used τονθορίζω. Because he said, I am the Bread which cometh down from heaven. This was a reasonable putting together of the three assertions: "I am the Bread of life" (John 7:35); "I have come down from heaven" (John 7:38); and "The bread of God is that which cometh down from heaven" (John 7:33).
"The Jews" did not misunderstand his meaning. They understood it perfectly, and rebelled against it.
