[James G. Bleak]
... And when a man takes a wife they enter this sacred order and covenant to observe all the rites in this. The man covenants to take more wives, the woman covenants to do the part of Sarah and gives her consent for him to take more wives. Hoped the young people would understand these things. A covenant not kept is a covenant broken. When we enter that covenant we must continue in it. Still there is no one here who will say you shall take more wives, that is left entirely with yourselves. Said we ought to express ourselves freely upon these things here for no one dare say any thing about them on the outside of this house. You take upon yourselves covenants to not speak outside of what takes place here. It is a grand thing to have a little common sense to guide us in these things.
