דָּרַ֨ךְ קַשְׁתּ֜וֹ כְּאוֹיֵ֗ב נִצָּ֤ב יְמִינוֹ֙ כְּצָ֔ר וַֽיַּהֲרֹ֔ג כֹּ֖ל מַחֲמַדֵּי־עָ֑יִן בְּאֹ֙הֶל֙ בַּת־צִיּ֔וֹן שָׁפַ֥ךְ כָּאֵ֖שׁ חֲמָתֽוֹ׃ (ס)
Armou o seu arco como inimigo, firmou a sua destra como adversário, e matou todo o que era formoso aos olhos; derramou a sua indignação como fogo na tenda da filha de Sião.
From David to Destruction
In Megillat Eichah, we express anger at Hashem in Pesukim such as “He drew His arrow like an enemy” (Eichah 2:4) and “He ambushes me like a bear, like a lion in waiting” (Eichah 3:4). We clarify in the Haftarah of Shabbat Chazon, however, that upon sober reflection, we realize that “Hashem is righteous in all His ways” (Tehillim 145:17).
Rashi
דרך כוכב A STAR COMETH OUT [OF JACOB] — Understand this as the Targum does (“a king will arise from Jacob”). The word דרך has the same meaning as in (Lamentations 2:4): “He has bent (דרך lit., trodden) his bow; this expression is used because the star shoots across [the heavens] as an arrow does when the bow is trodden. In O. F. destent. It is as much as to say, “Prosperity (a good fortune) will rise”.
