'Doth' in the Bible

We ought to give thanks to God always for you, brethren, as it is meet, because increase greatly doth your faith, and abound doth the love of each one of you all, to one another;

who is opposing and is raising himself up above all called God or worshipped, so that he in the sanctuary of God as God hath sat down, shewing himself off that he is God -- the day doth not come.

For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way.
