וְתָבֹאנָה֩ לָּ֨ךְ שְׁתֵּי־אֵ֥לֶּה רֶ֛גַע בְּי֥וֹם אֶחָ֖ד שְׁכ֣וֹל וְאַלְמֹ֑ן כְּתֻמָּם֙ בָּ֣אוּ עָלַ֔יִךְ בְּרֹ֣ב כְּשָׁפַ֔יִךְ בְּעָצְמַ֥ת חֲבָרַ֖יִךְ מְאֹֽד׃
Rashi on Isaiah
these two that you said that you would not sit as a widow and you would not know bereavement, shall suddenly come upon you.
Ibn Ezra on Isaiah
These two. The loss of the kingdom and the death of the children.
