וַיְהִ֣י הַיּ֔וֹם וַיִּזְבַּ֖ח אֶלְקָנָ֑ה וְנָתַ֞ן לִפְנִנָּ֣ה אִשְׁתּ֗וֹ וּֽלְכָל־בָּנֶ֛יהָ וּבְנוֹתֶ֖יהָ מָנֽוֹת׃
Nang dumating ang araw ng kapistahan, naghandog si Elkana, at binibigyan niya ng mga bahagi si Penina na kanyang asawa at ang lahat ng anak nitong lalaki at babae.
Rashi
It happened on the day. It happened on the festive day.
Metzudat David
And it was on that day: Meaning to say, when the day came that he would bring his sacrifices, Elkanah would sacrifice peace-offerings and he would give portions to Peninah, etc. from the sacrifice of the peace-offerings.
Radak
And it was on that day: The day of the set time; and likewise did Yonatan translate it [in the Targum] as, "the day of the set time." And in the homiletical teachings: Rabbi Yehoshua be Levi said, "This was the day of Shavuot."
