וּקְרָאתֶ֞ם בְּעֶ֣צֶם ׀ הַיּ֣וֹם הַזֶּ֗ה מִֽקְרָא־קֹ֙דֶשׁ֙ יִהְיֶ֣ה לָכֶ֔ם כָּל־מְלֶ֥אכֶת עֲבֹדָ֖ה לֹ֣א תַעֲשׂ֑וּ חֻקַּ֥ת עוֹלָ֛ם בְּכָל־מוֹשְׁבֹ֥תֵיכֶ֖ם לְדֹרֹֽתֵיכֶֽם׃
At sa mismong araw ding ito ay magpapahayag kayo; magkakaroon kayo ng isang banal na pagtitipon; huwag kayong gagawa ng anumang mabigat na gawain. Ito ay isang walang-hanggang batas sa lahat ng inyong mga tahanan para sa inyong mga salinlahi.
Sforno
חקת עולם לכל מושבותיכם, even though no manner of sacrificial offering could be offered in any of the countries to which Jews were eventually exiled, the “counting” part of this legislation would not be abandoned on account of this.
Rav Hirsch
V. 21. וקראתם וגו׳, zu diesem Satze fehlt das Objekt; denn מקרא קדש יהיה לכם ist ein selbständiger Satz. Es ist somit im Texte nicht gesagt, was verkündet werden soll. בעצם היום הזה will offenbar die hier angeordnete Festfeier mit מקרא קדש und איסור מלאכת עבודה an den Tag der Darbringung des, לחם ביכורים, an den fünfzigsten Tag der Omerzählung bleibend binden und feststellen und setzt dies Gründe voraus, die uns veranlassen könnten, die Festfeier an einem anderen Tage halten zu wollen. Beides Momente, deren Erklärung nur aus der Tradition zu schöpfen sein dürfte.
Chizkuni
וקראתם בעצם היום הזה מקרא קדש, “and you will proclaim a holy convocation on this very day.” The reason why the Torah does not spell out in which month this occurs, and on what date of this month, as it does with all the other festivals, is if it had done so, the people would not have been counting weeks and days, but would simply have contented themselves with observing the festival on its appropriate date. The counting was an important feature of these weeks as we have pointed out on verse 15. Nowadays, in the absence of the Temple, our being in exile, and having adopted (therefore?) a permanent calendar, the fiftieth day after the first day of Passover automatically occurs on the same date in the month of Sivan, the date on which the Ten Commandments (orally) were given to the Jewish people at Mount Sinai. In light of the fact that the counting is no longer associated with the date of Shavuot as that date was known, the benediction commencing with שהחיינו וקימנו לזמן הזה, “Who has kept us alive and well until this point in time,” is not recited.
