Deuteronomy 27:21

“Whoever lies with an animal shall surely be put to death.

‘Also you shall not lie with any animal to be defiled with it, nor shall any woman stand before an animal to mate with it; it is a perversion.

‘If there is a man who lies with an animal, he shall surely be put to death; you shall also kill the animal.

“Indeed all Israel has trespassed against Your law, even turning aside, not listening to Your voice; so the curse has been poured out on us, along with the oath which is written in the law of Moses the servant of God, for we have sinned against Him.

Otherwise if you bless in the spirit only, how will the one who fills the place of the uninformed say the “Amen” at your giving of thanks, since he does not know what you are saying?
