'Unlearned' in the Bible

Now when they saw the boldness of Peter and John, and had perceived that they were unlearned and ignorant men, they marveled. They recognized that they had been with Jesus.

Otherwise if you bless with the spirit, how will he who fills the place of the unlearned say the "Amen" at your giving of thanks, seeing he doesn't know what you say?

If therefore the whole assembly is assembled together and all speak with other languages, and unlearned or unbelieving people come in, won't they say that you are crazy?

But if all prophesy, and someone unbelieving or unlearned comes in, he is reproved by all, and he is judged by all.
