Hi! I don’t know if it is supposed to be options for this, but anyways, it is possible to answer and to interpret the text and the meaning of the word in context, so here it is.
In this excerpt, the word lodge helps the reader understand, that in case of a sudden exit of one of the Confederate Lords, his power in the Confederacy will stay inside, on the hands of the other members.
The idea of the whole excerpt from the Iroquois Constitution is to make clear for the reader that, if any of the members of the Confederacy leaves the council, his power of making decisions will remain in the hands of the other members. So, here, the word lodge means to stay, to remain. The power of the one that leaves will still be in the Confederacy.
