Genesis 22:4

ביום השלישי ON THE THIRD DAY — Why did God delay and not show it to him at once? So that people should not say, “He confused and confounded him suddenly and bewildered his mind. If, however, he had had time for consideration, he would not have obeyed” (Midrash Tanchuma, Vayera 22). וירא את המקום AND HE SAW THE PLACE — He saw a cloud lowering over the mountain (Genesis Rabbah 56:1).

בַּיּ֣וֹם הַשְּׁלִישִׁ֗י וַיִּשָּׂ֨א אַבְרָהָ֧ם אֶת־עֵינָ֛יו וַיַּ֥רְא אֶת־הַמָּק֖וֹם מֵרָחֹֽק׃

Then on the third day Avraham lifted up his eyes, and saw the place afar off.
