The man Elkanah, and all his house, went up to offer to Yahweh the yearly sacrifice, and his vow.
"She took him up with her, along with a three-year old bull." This does not mean that Hannah, alone, made the trip to Shiloh on this occasion, for  1 Samuel 1:3,21 establish the fact that Elkanah and his whole house made those yearly pilgrimages.  Hannah, however, is the principal actor on this particular occasion.
