Another explanation, “And Elokim spoke”: It is the severity of judgment, because the name Elokim is judgment, meaning Malchut, and she said to him, “I am HaShem,” which is another level, meaning Zeir Ainpin, which is mercy, and here all things are united, judgment and mercy together, which is great perfection. This is what is written, “And he said to him, I am HaShem,” which is the measure of mercy. Rabbi Shimon said, if it were written, “And Elokim spoke to Moses, I am HaShem,” it would have said that judgment and mercy are united together for him. But it is not written like that, but rather, “And Elokim spoke to Moses” at the beginning, and then, “And he said to him, I am HaShem,” meaning that they are of a different level than the other, and they are not judgment and mercy united together.
