"Flock of God, the son of Barzillai, the Meholathite, to whom" Saul gave in marriage his daughter Merab (1 Sam. 18:19). The five sons that sprang from this union were put to death by the "Gibeonites (2 Sam. 21:8, 9. Here it is said that Michal "brought" "up" [R.V., "bare"] these five sons, either that she treated them" "as if she had been their own mother, or that for "Michal" we" "should read "Merab," as in 1 Sam. 18:19)."
