וְרָעוּ֙ בְּכוֹרֵ֣י דַלִּ֔ים וְאֶבְיוֹנִ֖ים לָבֶ֣טַח יִרְבָּ֑צוּ וְהֵמַתִּ֤י בָֽרָעָב֙ שָׁרְשֵׁ֔ךְ וּשְׁאֵרִיתֵ֖ךְ יַהֲרֹֽג׃
E os primogênitos dos pobres serão apascentados, e os necessitados se deitarão seguros; mas farei morrer de fome a tua raiz, e será destruído o teu restante.
Rashi on Isaiah
And the first born of the poor shall graze In his days, the princes of Israel, who are now poor because of you, shall graze. “Firstborn,” is an expression of princes. Comp. (Ps. 89:28) “Also, I will appoint him My firstborn.”
Ibn Ezra on Isaiah
בכורי דלים The firstborn of the poor. Israel, who had become impoverished sooner than any other nation,—Israel shall enjoy abundance and safety; the opposite fate shall befall the Philistines.
