אַל־תִּֽירְאִי֙ תּוֹלַ֣עַת יַֽעֲקֹ֔ב מְתֵ֖י יִשְׂרָאֵ֑ל אֲנִ֤י עֲזַרְתִּיךְ֙ נְאֻם־יְהוָ֔ה וְגֹאֲלֵ֖ךְ קְד֥וֹשׁ יִשְׂרָאֵֽל׃
蟲一般的雅各啊，以色列人哪，不要懼怕！永恆者說：我必幫助你；你的救贖者就是以色列的聖者。
Midrash Lekach Tov
"That you shall accept from them": Not donation of grain, wine, and oil, but gold, silver, and bronze. The Blessed, Holy One said: I set up thirteen things for you in Egypt; you, too, should offer thirteen. The thirteen which [God] did in Egypt are written down by Ezekiel: "I clothed you with embroidered garments, and gave you sandals of dolphin leather to wear, and wound fine linen about your head, and dressed you in silks. I decked you out in finery and put bracelets on your arms and a chain around your neck. I put a ring in your nose, and earrings in your ears, and a splendid crown on your head....the choice flour, the oil, and the honey, which I had provided for you to eat" (Ezekiel 16:10-12, 19) -- which come to thirteen. You, too, should offer me thirteen things: gold, silver, bronze; blue, purple, and crimson yarns; fine linen, goats’ hair; tanned ram skins, dolphin skins, and acacia wood, oil for lighting, spices for the anointing oil and for the aromatic incense; lapis lazuli and other stones for setting" (Exodus 25:4-7).....
Rashi
O worm of Jacob Heb. תּוֹלַעַת. The family of Jacob, which is weak like a worm, which has no strength except in its mouth. תּוֹלַעַת is vermener in O.F., [vermisseau in Modern French, a worm].
Ibn Ezra
Thou worm Jacob, Israel had been considered by the Babylonians as worms. Fear not, that you will be killed together with the Babylonians.
