וַיֹּ֥אמֶר שְׁמוּאֵ֖ל מֶ֣ה עָשִׂ֑יתָ וַיֹּ֣אמֶר שָׁא֡וּל כִּֽי־רָאִיתִי֩ כִֽי־נָפַ֨ץ הָעָ֜ם מֵעָלַ֗י וְאַתָּה֙ לֹא־בָ֙אתָ֙ לְמוֹעֵ֣ד הַיָּמִ֔ים וּפְלִשְׁתִּ֖ים נֶאֱסָפִ֥ים מִכְמָֽשׂ׃
Rashi on I Samuel
What have you done? Did I not say to you, "I will go down to you to offer the burnt-offering?" I will offer it up, and not you.
Rashi on I Samuel
At the appointed day. At the beginning of the [appointed] day.
