Tanakh sur Le Lévitique 23:15

וּסְפַרְתֶּ֤ם לָכֶם֙ מִמָּחֳרַ֣ת הַשַּׁבָּ֔ת מִיּוֹם֙ הֲבִ֣יאֲכֶ֔ם אֶת־עֹ֖מֶר הַתְּנוּפָ֑ה שֶׁ֥בַע שַׁבָּת֖וֹת תְּמִימֹ֥ת תִּהְיֶֽינָה׃

Puis, vous compterez chacun, depuis le lendemain de la fête, depuis le jour où vous aurez offert l’ômer du balancement, sept semaines, qui doivent être entières;

I Samuel

It was the day after the New Moon, the second [day], and Dovid's place was empty. Shaul said to Yonoson, his son, "Why has the son of Yishay not come to the meal neither yesterday nor today?"

Leviticus

He shall wave the omer before Adonoy that it be favorably accepted for you. On the day after the day of rest (Pesach), the kohein shall wave it.

Numbers

On the day of the first fruits when you bring a new meal-offering to Adonoy on your Festival of Weeks, there shall be a sacred holiday to you when you shall not do any work of consequence.
