טֽוֹב־עַ֭יִן ה֣וּא יְבֹרָ֑ךְ כִּֽי־נָתַ֖ן מִלַּחְמ֣וֹ לַדָּֽל׃
선한 눈을 가진 자는 복을 받으리니 이는 양식을 가난한 자에게 줌이니라
Kol HaTor
(Prov. 22:9) “one who has a good [bountiful] eye will be blessed” -- (in Likutei Hagr’a). That means 999 in the sefira Yesod, which refers to Yosef, as explained above, because he gave of his bread to the poor.
