Most interpreters of this story have ignored the inherent power differential between a king and one of his female subjects; and this king was invested not only with political power, but spiritual power. There is no word here that Bathsheba had done anything to displease God. She is not a co-conspirator. This deed was David’s and David’s alone.
Being queen did not give Esther the connection with the king you might expect. Because if anyone, including the queen, approached the king without his permission, you could be put to death. Perhaps God has put you here for exactly this moment, for just such a time as this!
