וַיֹּ֣אמֶר אֵלֶ֔יהָ עֲמֹ֖ד פֶּ֣תַח הָאֹ֑הֶל וְהָיָה֩ אִם־אִ֨ישׁ יָב֜וֹא וּשְׁאֵלֵ֗ךְ וְאָמַ֛ר הֲיֵֽשׁ־פֹּ֥ה אִ֖ישׁ וְאָמַ֥רְתְּ אָֽיִן׃
그가 또 가로되 장막문에 섰다가 만일 사람이 와서 네게 묻기를 여기 어떤 사람이 있느냐 하거든 너는 없다 하라 하고
Rashi
Stand at the entrance to the tent. Be zealous about it. Some interpret עֲמֹד [lit. "stand"] as לַעֲמוֹד, "to stand".11This interpretation adds the ל, which does not actually appear in the text, so that the reading is “He told her to stand at the entrance.” According to the literal textual interpretation, the reading is, “He told her, stand at the entrance.” This is problematic, as the masculine עֲמוֹד, rather than עִמֽדִי, is inappropriate in addressing a woman. The additional ל solves this difficulty by transforming the command, עֲמוֹד, “stand”, into the infinitive לַעֲמוֹד, “to stand.”

Stand: It is an infinitive: And he said to her to stand at the entrance of the tent.
