tc The MT has simply “and Cain said to Abel his brother,” omitting Cain’s words to Abel. It is possible that the elliptical text is original. Perhaps the author uses the technique of aposiopesis, “a sudden silence” to create tension. In the midst of the story the narrator suddenly rushes ahead to what happened in the field. It is more likely that the ancient versions (Samaritan Pentateuch, LXX, Vulgate, and Syriac), which include Cain’s words, “Let’s go out to the field,” preserve the original reading here. After writing אָחִיו (’akhiyv, “his brother”), a scribe’s eye may have jumped to the end of the form בַּשָּׂדֶה (basadeh, “to the field”) and accidentally omitted the quotation. This would be an error of virtual homoioteleuton. In older phases of the Hebrew script the sequence יו (yod-vav) on אָחִיו is graphically similar to the final ה (he) on בַּשָּׂדֶה.
