Open unto us - This is not to be understood as implying that any will come after the righteous shall be admitted into the kingdom, and claim admission then. It is a part of the parable to illustrate the general truth inculcated, or to prepare the way for what is afterwards said, and to keep up the narrative and make it consistent.
