1 Samuel 1:21

All his house, i.e. his wife Peninnah, and his children, which are ofttimes called a man's house in Scripture, Hannah only and her child excepted, as it here follows. The yearly sacrifice; that solemn sacrifice which was offered up once every year; probably the paschal lamb, which is oft called a sacrifice, as Exodus 12:27, Exodus 34:25. And his vow; by which it appears, though it was not expressed before, that he heard and consented to her vow, which was necessary to make it obligatory, Num 30, and that he added a vow of his own, of some singular sacrifice to be offered, if God answered his prayers.
