'Doth' in the Bible

Doth not even nature itself teach you, that, if a man have long hair, it is a dishonor to him?

doth not behave itself unseemly, seeketh not its own, is not provoked, taketh not account of evil;

If after the manner of men I fought with beasts at Ephesus, what doth it profit me? If the dead are not raised, let us eat and drink, for to-morrow we die.

Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
