הָרִ֣יעוּ לַֽ֭יהוָה כָּל־הָאָ֑רֶץ פִּצְח֖וּ וְרַנְּנ֣וּ וְזַמֵּֽרוּ׃
Acclamez l’Éternel, toute la terre, entonnez des cantiques, chantez des hymnes!
Rashi
בחצריהם BY THEIR ENCLOSURES — Unwalled towns. In the Targum it is rendered by בפצחיהון because they are מפוצחים, which means “open”; similar in meaning to (Psalms 98:4) ‘‘Open your mouths (פצחו) and sing for joy”.
