Whom she brought up. Literally, “whom she bore.” There is no valid reason for translating the Hebrew verb, yalad, employed in this phrase, “to bring up.” The difficulty, of course, is that Adriel was the husband of Merab, not of Michal (1 Sam. 18:19). The simplest solution seems to be to accept the reading of two Hebrew manuscripts, one of the recensions of the LXX, and the Syriac, which here read “Merob” for “Michal.” Merab was the one who was originally to be given to David, but who was given to Adriel instead, David receiving Michal (1 Sam. 18:20-27). Unless Michal had children through her marriage to Phalti (1 Sam. 25:44), she died childless (2 Sam. 6:23).
