John Wesley on 1 Samuel 2:5

Hired themselves out for bread - It is the same thing which is expressed both in divers metaphors in the foregoing, and following verses. Ceased - That is, ceased to be hungry. Seven - That is, many, as seven is often used. She speaks in the prophetick style, the past time, for the future; for though she had actually born but one, yet she had a confident persuasion that she should have more, which was grounded either upon some particular assurance from God; or rather upon the prayer or prediction of Eli. She - That is, Peninnah. Feeble - Either because she was now past child - bearing: or, because divers of her children, which were her strength and her glory, were dead, as the Hebrew doctors relate.
