Do not appear at the Temple during Passover, the Feast of Weeks, and the Feast of Tabernacles without offerings

"Three times in a year all your males shall appear before the LORD your God in the place which He chooses, at the Feast of Unleavened Bread and at the Feast of Weeks and at the Feast of Booths, and they shall not appear before the LORD empty-handed.

Hebrew

שָׁלוֹשׁ פְּעָמִים בַּשָּׁנָה יֵרָאֶה כָל־זְכוּרְךָ אֶת־פְּנֵי יְהוָה אֱלֹהֶיךָ בַּמָּקוֹם אֲשֶׁר יִבְחָר בְּחַג הַמַּצּוֹת וּבְחַג הַשָּׁבֻעוֹת וּבְחַג הַסֻּכּוֹת וְלֹא יֵרָאֶה אֶת־פְּנֵי יְהוָה רֵיקָם׃ ‬
