כִּ֣י לֹ֧א יַעֲשֶׂ֛ה אֲדֹנָ֥י יְהוִ֖ה דָּבָ֑ר כִּ֚י אִם־גָּלָ֣ה סוֹד֔וֹ אֶל־עֲבָדָ֖יו הַנְּבִיאִֽים׃
주 여호와께서는 자기의 비밀을 그 종 선지자들에게 보이지 아니하시고는 결코 행하심이 없으시리라
Rashi
For the Lord God does nothing unless He has revealed His secret—That secret to His servants, the prophets.
Tze'enah Ure'enah
“The Lord God does nothing, etc.” [3:7]. God does not do anything without letting His prophets know. Since the prophets previously told that you should be pious, in the hope that you will be protected from all evil.
