דָּרַ֨ךְ קַשְׁתּ֜וֹ כְּאוֹיֵ֗ב נִצָּ֤ב יְמִינוֹ֙ כְּצָ֔ר וַֽיַּהֲרֹ֔ג כֹּ֖ל מַחֲמַדֵּי־עָ֑יִן בְּאֹ֙הֶל֙ בַּת־צִיּ֔וֹן שָׁפַ֥ךְ כָּאֵ֖שׁ חֲמָתֽוֹ׃ (ס)
Il a bandé son arc comme un ennemi, brandi sa droite comme un adversaire; il a fait périr tous ceux qui étaient un délice pour les yeux; dans la tente de la fille de Sion il a déversé comme un feu son courroux.
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”.
