וַֽיִּשְׁמְע֞וּ אֶת־ק֨וֹל יְהוָ֧ה אֱלֹהִ֛ים מִתְהַלֵּ֥ךְ בַּגָּ֖ן לְר֣וּחַ הַיּ֑וֹם וַיִּתְחַבֵּ֨א הָֽאָדָ֜ם וְאִשְׁתּ֗וֹ מִפְּנֵי֙ יְהוָ֣ה אֱלֹהִ֔ים בְּת֖וֹךְ עֵ֥ץ הַגָּֽן׃
Lalu mereka mendengar suara Allah Yang Mahakekal yang bergerak di taman menjelang sejuknya hari. Manusia itu dan istrinya bersembunyi dari hadapan Allah Yang Mahakekal di antara pohon-pohon di taman.
Rashi
וישמעו AND THEY HEARD — There are many Midrashic explanations and our Teachers have already collected them in their appropriate places in Genesis Rabbah and in other Midrashim. I, however, am only concerned with the plain sense of Scripture and with such Agadoth that explain the words of Scripture in a manner that fits in with them. וישמעו AND THEY HEARD — What did they hear? They heard the sound of the Holy One, blessed be He, as He walked in the garden (see Genesis Rabbah 19:12).
Chizkuni
מתהלך בגן, “the sound of G-d’s voice appeared to take a walk in the garden” This expression describing the movement of sound, occurs elsewhere also. Examples are: Exodus 19,19, קול השופר הולך, “as the sound of the shofar became progressively stronger;” it also occurs in Jeremiah 46,22, קולה כנחש ילך, “she rustles like a snake.”
Rashbam
וישמעו את קול ה' אלוקים מתהלך בגן לרוח היום, referring to the author’s commentary on Exodus 14,30, it appears that he understands the word מתהלך, as does Rabbi Chalfan in Bereshit Rabbah 19,7 where that Rabbi says that the word מתהלך modifies the word קול.
