וְעַד־זִקְנָה֙ אֲנִ֣י ה֔וּא וְעַד־שֵיבָ֖ה אֲנִ֣י אֶסְבֹּ֑ל אֲנִ֤י עָשִׂ֙יתִי֙ וַאֲנִ֣י אֶשָּׂ֔א וַאֲנִ֥י אֶסְבֹּ֖ל וַאֲמַלֵּֽט׃ (ס)
Hanggang sa inyong katandaan ay Ako pa rin iyon, at hanggang sa pumuti ang inyong buhok ay papasanin Ko kayo; Ako ang gumawa, at Ako ang magbubuhat, Ako ang magpapasan, at Ako ang magliligtas.
Rashi
And until old age that you have aged and your strength is depleted, that you have no merit, I am the same with My mercy and with My trait of goodness to save you and to bear you and to carry you and deliver you. Since he says regarding their deity, that it is carried and also that it cannot deliver its burden, he says, “But I bear others, and I will deliver My burden.”
Ibn Ezra
And even to old age, etc. This is a figurative expression; it means since the day they had become the people of the Lord for ever.
Ibn Ezra
I have made the Israelites; I am, therefore, not like the gods of Babylon; the Babylonians make their gods. And I will carry and deliver the Israelites; while the idols cannot deliver the burden.
