John Wesley on 1 Samuel 2:31

Arm - That is, I will take away thy strength, or all that in which thou placest thy confidence, either, the ark, which is called God's strength, Psal 78:61, and was Eli's strength, who therefore was not able to bear the very tidings of the loss of it. Or, his priestly dignity or employment, whence he had all his honour and substance. Or rather, his children, to whom the words following here, and in the succeeding verses, seem to confine it. Father's house - That is, thy children's children, and all thy family which was in great measure accomplished, 1Sam 22:16, &c.
