Ibn Ezra on Deuteronomy 21:3/אבן עזרא על דברים כ״א:ג׳
אעגלת בקר אשר לא עבד בה. לחרוש:
1A HEIFER OF THE HERD, WHICH HATH NOT BEEN WROUGHT WITH. Never used for plowing.4 (which hath not been wrought with). I.E. interprets ubbad as referring to plowing, for Scripture later uses a word from this root in the sense of ploughed. Compare, lo ye’aved bo (which may neither be plowed) (v. 4).
בולא משכה בעול. להביא אבנים כמנהג העגלות:
2AND WHICH HATH NOT DRAWN IN THE YOKE. To bring stones, as is the practice with heifers.5
