שֵׁ֥שֶׁת יָמִ֖ים תֹּאכַ֣ל מַצּ֑וֹת וּבַיּ֣וֹם הַשְּׁבִיעִ֗י עֲצֶ֙רֶת֙ לַיהוָ֣ה אֱלֹהֶ֔יךָ לֹ֥א תַעֲשֶׂ֖ה מְלָאכָֽה׃ (ס)
Six days thou shalt eat unleavened bread; and on the seventh day shall be a solemn assembly to the LORD thy God; thou shalt do no work therein.
Targum Jonathan on Deuteronomy
On the first day thou shalt offer the omer, and eat unleavened cakes of the old corn; but in the six remaining days you may begin to eat unleavened cakes of the new corn, and on the seventh day you shall assemble with thanksgiving before the Lord your God; no work shall you perform.
