1 Samuel 2:5

She speaks in the prophetic 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; which, though it be mentioned after this song, 1 Samuel 2:20, yet in all probability was spoken before it, even upon the parents presentation of the child to Eli, 1 Samuel 1:25, it not being likely that she would sing this song in Eli's presence, or before he had given his answer to her speech delivered 1 Samuel 1:26, there being nothing more frequent than such transpositions in Scripture. And the experience she had of the strange and speedy accomplishment of his former prophecy made her confidently expect the same issue from the latter. She that hath many children, i.e. Peninnah. Is waxed feeble; either because she was now past child-bearing, and impotent for procreation; or because divers of her children, which were her strength and her glory, were dead, as the Hebrew doctors relate.
