Flock of God, the son of Barzillai, the Meholathite, to whom Saul gave in marriage his daughter Merab (1 Samuel 18:19
). The five sons that sprang from this union were put to death by the Gibeonites (2 Samuel 21:8,9
. Here it is said that Michal "brought up" [RSV, "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 Samuel 18:19
