שָׁמַ֤עְתָּֽ חֲזֵה֙ כֻּלָּ֔הּ וְאַתֶּ֖ם הֲל֣וֹא תַגִּ֑ידוּ הִשְׁמַעְתִּ֤יךָ חֲדָשׁוֹת֙ מֵעַ֔תָּה וּנְצֻר֖וֹת וְלֹ֥א יְדַעְתָּֽם׃
Thou hast heard, see, all this; And ye, will ye not declare it? I have announced unto thee new things from this time, Even hidden things, which thou hast not known.
Rashi on Isaiah
You have heard, see all of it You have heard the first ones that I told; see that all of them have come about.
Ibn Ezra on Isaiah
Thou hast heard, see all this. What thou hast heard, all has come.
Rashi on Isaiah
and you, will you not tell and testify for Me that nothing failed?
