'Wert' in the Bible

If thou wert pure and upright: Surely now he would awake for thee, And make the habitation of thy righteousness prosperous.

Oh that thou wert as my brother, That sucked the breasts of my mother! When I should find thee without, I would kiss thee; Yea, and none would despise me.

I know thy works, that thou art neither cold nor hot: I would thou wert cold or hot.
