לְ֠שַׁלַּח אִ֣ישׁ אֶת־עַבְדּ֞וֹ וְאִ֧ישׁ אֶת־שִׁפְחָת֛וֹ הָעִבְרִ֥י וְהָעִבְרִיָּ֖ה חָפְשִׁ֑ים לְבִלְתִּ֧י עֲבָד־בָּ֛ם בִּיהוּדִ֥י אָחִ֖יהוּ אִֽישׁ׃
그 언약은 곧 사람으로 각기 히브리 남녀 노비를 놓아 자유케 하고 그 동족 유다인으로 종을 삼지 못하게 한 것이라
Ibn Ezra

Radak
ועבדום, the Egyptians will enslave them, and will oppress them. It is not unusual to apply the prefix ב to people who have been enslaved, as we find a similar construction in Leviticus 25,39 לא תעבוד בו עבודת עבד, “do not make him perform the menial duties performed by a slave.” Or Jeremiah 34,10, לבלתי עבד בם, “not to keep them enslaved.” The word עבדם i.e. עבודה is used to describe the status of the person described, whereas the word וענו refers to the manner in which such slaves would be treated.
