25As touching the Gentiles which believe, we have written and concluded that they observe no such thing, save only that they keep themselves from things offered to idols, and from blood, and from strangled, and from fornication.
(Acts 21:25)
28For it seemed good to the Holy Ghost, and to us, to lay upon you no greater burden than these necessary things; 29That ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication: from which if ye keep yourselves, ye shall do well. Fare ye well.
(Acts 15:28+29)
In the book of Acts, the gentiles are instructed to abstain from things strangled.
The Noah Webster 1828 dictionary defines strangled as:
STRANGLE, verb transitive [Latin]
1. To choke; to suffocate; to destroy life by stopping respiration.
Our Saxon ancestors compelled the adulteress to strangle herself.
2. To suppress; to hinder from birth or appearance.
I have also read that strangled meat refers to meat that hasn't had the blood drained out.
In the book of John, Jesus invites the disciples to eat fish, but if the fish were trawled in a net from the water, wouldn't they suffocate?
10Jesus saith unto them, Bring of the fish which ye have now caught. 11Simon Peter went up, and drew the net to land full of great fishes, an hundred and fifty and three: and for all there were so many, yet was not the net broken. 12Jesus saith unto them, Come and dine. And none of the disciples durst ask him, Who art thou? knowing that it was the Lord. 13Jesus then cometh, and taketh bread, and giveth them, and fish likewise.
(John 21:10-13)
My question concerns what would be termed as a strangled meat?
Are meats termed strangled meats because of the way they die (suffocation) or are they strangled meats because of another reason - maybe to do with the way the meat was prepared; if someone didn't drain the blood out from the fish after it was caught?
Would it be foods like shellfish/molluscs, or animals that have their necks wrung or are shot without being drained of blood?
