Vayishlach - What's with the dots?
(ד) וַיָּ֨רָץ עֵשָׂ֤ו לִקְרָאתוֹ֙ וַֽיְחַבְּקֵ֔הוּ וַיִּפֹּ֥ל עַל־צַוָּארָ֖ו וַׄיִּׄשָּׁׄקֵ֑ׄהׄוּׄ וַיִּבְכּֽוּ׃
(4) Esau ran to greet him. He embraced him and, falling on his neck, he kissed him; and they wept.
(ב) וישקהו נָקוּד עָלָיו; וְיֵשׁ חוֹלְקִין בַּדָּבָר הַזֶּה בְּבָרַיְתָא דְּסִפְרֵי, יֵשׁ שֶׁדָּרְשׁוּ נְקֻדָּה זוּ, שֶׁלֹּא נְשָׁקוֹ בְּכָל לִבּוֹ, אָמַר רַבִּי שִׁמְעוֹן בֶּן יוֹחָאִי, הֲלָכָה הִיא בְּיָדוּעַ שֶׁעֵשָׂו שׂוֹנֵא לְיַעֲקֹב, אֶלָּא שֶׁנִּכְמְרוּ רַחֲמָיו בְּאוֹתָהּ שָׁעָה וּנְשָׁקוֹ בְּכָל לִבּוֹ (ספרי במדבר):
(2) וישקהו AND HE KISSED HIM — Dots are placed above the letters of this word, and a difference of opinion is expressed in the Baraitha of Sifré (בהעלותך) as to what these dots are intended to suggest: some explain the dotting as meaning that he did not kiss him with his whole heart, whereas R Simeon the son of Johai said: Is it not well-known that Esau hated Jacob? But at that moment his pity was really aroused and he kissed him with his whole heart. (Sifrei Bamidbar 69.2)

Ralbag

To my mind, the dots that are above (the word) ‘elav,’ and similar examples, appear to me to indicate an intermediate situation between the presence of the dotted word and its absence. For the dots are placed over a word [in order] to erase that which appears under the dots. But since the word remains written in the text with the dots above it, it indicates that it is not erased altogether, nor is it written in its [usual] entire manner.
