וְעַתָּ֗ה אָבִי֙ הֶעְמִ֤יס עֲלֵיכֶם֙ עֹ֣ל כָּבֵ֔ד וַאֲנִ֖י אוֹסִ֣יף עַֽל־עֻלְּכֶ֑ם אָבִ֗י יִסַּ֤ר אֶתְכֶם֙ בַּשּׁוֹטִ֔ים וַאֲנִ֕י אֲיַסֵּ֥ר אֶתְכֶ֖ם בָּעַקְרַבִּֽים׃
«『現在，我父親使你們負沉重的軛，我卻要使你們的軛更重；我父親用鞭子責打你們，我卻要用蠍子鞭責打你們。』»
Rashi
and one I called Destoyers Rehoboam told [his kingdom] that he would flog them with scorpions (I Kings 12:11). [Zechariah] calls their rulers staffs because it is customary to lead flocks with staffs.
Rashbam
לשכים בעיניכם, an expression describing thorns and thistles. These pierce one’s eyes as described in Hoseah 2,8 הנני סך את דרכך בסירים, “here I am going to hedge up her roads with thorns.” We have further support for this in the Book of Joshua 23,13 והיו לכם לפח ולמוקש ולשוטט בצדיכם ולצנינים בעיניכם, “they shall become a snare and a trap for you, a scourge to your sides and thorns in your eyes.” We have a similar threat uttered by Rechavam Solomon’s son who told the people: “my father disciplined you with whips, whereas I intend to flog you with scorpions” (Kings I 12,11).
