Why Jacob Bowed Seven Times and the Dotted Kiss of Esau

Another interpretation: why seven? He said to him: see yourself as if you were placed within seven enclosures, sitting and judging, and I am being judged before you, and you are filled with compassion toward me. "And Esau ran to meet him and embraced him and fell on his neck and kissed him" (Genesis 33:4). There are dots above it. Rabbi Simeon ben Elazar said: wherever you find the writing exceeding the dots, you expound the writing; the dots exceeding the writing, you expound the dots. And here neither the writing exceeds the dots nor the dots exceed the writing, which teaches that he did not kiss him with his whole heart. Rabbi Yannai says: it teaches that he did not seek to kiss him but to bite him, and Jacob's neck became like marble, and the teeth of that wicked man were blunted. And what does the text mean by "and they wept"? This one wept over his neck and that one wept over his teeth.
