Ramban on Genesis 18:17/רמב"ן על בראשית י״ח:י״ז
אוַה' אָמַר אֶל צְבָא הַשָּׁמַיִם הָעוֹמְדִים עָלָיו אוֹ אֶל הַמַּלְאָכִים הַשְּׁלוּחִים. וְיִתָּכֵן שֶׁהוּא הַמַּחְשָׁבָה, כִּי חָשַׁב שֶׁלֹּא יִתְכַּסֶּה מִמֶּנּוּ מִפְּנֵי הַטְּעָמִים הַלָּלוּ, וְכֵן "וַאֲנִי אָמַרְתִּי בִּדְמִי יָמַי" (ישעיהו לח י), וְכֵן "וַיֹּאמֶר לְהַכּוֹת אֶת דָּוִד" (שמואל ב כא טז), וְכֵן כָּל אֲמִירָה עִם הַלֵּב – מַחְשָׁבָה:
1AND THE ETERNAL SAID. I.e., to the host of heaven standing by Him,111 or to the angel messengers.It is possible that the word amar (He said) refers to thought, meaning that He thought He should not keep it hidden from Abraham on account of these reasons. Similarly: I ‘said,’ in the noontide of my days I shall go;112 And he ‘said’ to slay David.113 Likewise all expressions of speaking within the heart refer to thought.114, further, 27:41. See Ramban there.
