Then the Lord opened the donkey’s mouth,
and it said to Balaam, “What have I done to you to make you beat me these three
times?” Numbers 22:28
Donkeys can’t talk, but if God wants a
donkey to think and reason, then yes a donkey can talk. God created that donkey and he can modify
that creation if he wants to.
The
way the donkey responded indicated that the donkey was thinking for
himself. This was not an angel talking
through the donkey. The donkey talked about
his past loyalty to Balaam and referred to himself in the first person.
It’s
unusual and can be done only if God permits it to happen.
