'Doth' in the Bible

beloved, concerning all things I desire thee to prosper, and to be in health, even as thy soul doth prosper,

I did write to the assembly, but he who is loving the first place among them -- Diotrephes -- doth not receive us;

because of this, if I may come, I will cause him to remember his works that he doth, with evil words prating against us; and not content with these, neither doth he himself receive the brethren, and those intending he doth forbid, and out of the assembly he doth cast.
