וַתֹּֽאמֶר־לָ֥הּ בַּת־פַּרְעֹ֖ה לֵ֑כִי וַתֵּ֙לֶךְ֙ הָֽעַלְמָ֔ה וַתִּקְרָ֖א אֶת־אֵ֥ם הַיָּֽלֶד׃
Sinabi sa kanya ng anak na babae ni Faraon: “Humayo ka.” At humayo ang dalaga at tinawag niya ang ina ng bata.
Rashi
ותלך העלמה AND THE YOUNG WOMAN WENT — she went eagerly and with vigour (עלמות) like a young man (עלם) (cf. Sotah 12b).
Chizkuni
ותלך העלמה, “the young lady went, etc.” The reason why the Torah calls her by the description עלמה, is because she concealed the fact that she was the baby’s sister.
