טֽוֹב־עַ֭יִן ה֣וּא יְבֹרָ֑ךְ כִּֽי־נָתַ֖ן מִלַּחְמ֣וֹ לַדָּֽל׃
眼目慷慨的人必蒙賜福，因為他將自己的食物分給貧窮人。
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.
