כִּ֤י שֶׁ֨מֶשׁ ׀ וּמָגֵן֮ יְהוָ֪ה אֱלֹ֫הִ֥ים חֵ֣ן וְ֭כָבוֹד יִתֵּ֣ן יְהוָ֑ה לֹ֥א יִמְנַע־ט֝֗וֹב לַֽהֹלְכִ֥ים בְּתָמִֽים׃
因為永恆者上帝是太陽,是盾牌;永恆者賜下恩惠和榮耀,他必不將任何好處留下不給行事完全的人。
Rashi
For a sun and a shield שמש may be interpreted according to its apparent meaning, but Midrash Psalms interprets it as an expression of the points of the wall.
