The people in them eat snakes and in another picture, a scorpion.
I now think of Mark 16:18 .
The people are unharmed even though they eat snakes and scorpion.
Mark 16:14 Afterward he appeared unto the eleven as they sat at meat, and upbraided them with their unbelief and hardness of heart, because they believed not them which had seen him after he was risen.
Mark 16:15 And he said unto them, Go ye into all the world, and preach the gospel to every creature.
Mark 16:16 He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
Mark 16:17
And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;
Mark 16:18
They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.
Mark 16:19 So then after the Lord had spoken unto them, he was received up into heaven, and sat on the right hand of God.
Mark 16:20 And they went forth, and preached every where, the Lord working with them, and confirming the word with signs following. Amen.
When you read the full context then you will see that even if one gets bit by a snake or stung by a scorpion or accidentally drink any deadly thing, if they truly trust in God they will recover of these poisonous things. Some people do eat snakes and scorpions, but they remove the poison from them before they do.
