I just don't see keeping a snake in a very small box, & on the show it seems that's where they keep them. To me keeping snakes & or small animals in a small box seems to be inhumane, mistreating the snake or animal.
I suppose it may be true after they've handled the snake for some time it might gentle down somewhat & not be as lively & or it could be from poor health.
Besides that to me their way is ridiculous, & not the least bit biblical.
Yes, I think the poor living conditions of the snakes is a factor.
No doubt, what they are doing is a total twisting and misinterpretation of one verse in the Bible. Considering they are in gross error with regards to the primary point of Scripture, that of salvation, it's little wonder they are in such great error elsewhere.
