Ezek 46:9

וּבְב֨וֹא עַם־הָאָ֜רֶץ לִפְנֵ֣י יְהוָה֮ בַּמּֽוֹעֲדִים֒ הַבָּ֡א דֶּרֶךְ־שַׁ֨עַר צָפ֜וֹן לְהִֽשְׁתַּחֲוֺ֗ת יֵצֵא֙ דֶּרֶךְ־שַׁ֣עַר נֶ֔גֶב וְהַבָּא֙ דֶּרֶךְ־שַׁ֣עַר נֶ֔גֶב יֵצֵ֖א דֶּרֶךְ־שַׁ֣עַר צָפ֑וֹנָה לֹ֣א יָשׁ֗וּב דֶּ֤רֶךְ הַשַּׁ֨עַר֙ אֲשֶׁר־בָּ֣א ב֔וֹ כִּ֥י נִכְח֖וֹ יצאו יֵצֵֽא׃

When the people of the land come before the LORD at the appointed feasts, whoever enters by the north gate to worship must go out by the south gate, and whoever enters by the south gate must go out by the north gate. No one is to return through the gate by which he entered, but each must go out by the opposite gate.
