והיה. לְשׁוֹן הוֹוֶה: והיה — This expresses an action continually going on (“and it used to be”),
כצאת. מֹשֶׁה מִן הַמַּחֲנֶה לָלֶכֶת אל האהל: כצאת משה WHEN MOSES WENT OUT from the camp in order to go אל האהל INTO THE TENT, יקומו כל העם ALL THE PEOPLE ROSE UP — they used to stand up before him and did not sit down until he vanished from their sight (Hebrew: was hidden from them).
יקומו כל העם. עוֹמְדִים מִפָּנָיו, וְאֵין יוֹשְׁבִין עַד שֶׁנִּתְכַּסָּה מֵהֶם: והביטו אחרי משה AND THEY LOOKED AFTER MOSES — Not sneeringly but out of admiration; they exclaimed: Happy is the human being (Hebrew: one born of woman) who is so sure that the Shechina will enter the door of his tent after him (cf. Kiddushin 33b; Midrash Tanchuma, Ki Tisa 27, Exodus Rabbah 51:6).
והביטו אחרי משה. לְשֶׁבַח – אַשְׁרֵי יְלוּד אִשָּׁה שֶׁכָּךְ מֻבְטָח שֶׁהַשְּׁכִינָה תִכָּנֵס אַחֲרָיו לְפֶתַח אָהֳלוֹ: And they would gaze after Moshe — in an admiring way, [saying, in effect:] “Fortunate is one born of woman who is assured that the Shechinah will follow him into the entranceway of his tent.”
