פירוש על שמואל א 1:22

When [the boy] will be weaned. At the end of twenty-two (other versions, twenty-four) months, for that is the period for a child to nurse.

Did not go up: That year.

Until the boy will be weaned: Until the end of his nursing, and that is the twenty-four months that an infant nurses. And even though they were obligated to bring him [to Shiloh] on account of, "every male shall appear" (Exodus 23:17) - our Rabbis, may their memory be blessed, said it was because she saw that he was pampered and weak, so she was concerned lest he fall sick because of the travel.
