וְהִשְׁתַּחֲו֣וּ עַם־הָאָ֗רֶץ פֶּ֚תַח הַשַּׁ֣עַר הַה֔וּא בַּשַּׁבָּת֖וֹת וּבֶחֳדָשִׁ֑ים לִפְנֵ֖י יְהוָֽה׃
Les jours de Sabbat et de Néoménie, la population du pays se prosternera à l’entrée de cette même porte, devant l’Éternel.
Rashi
And the people of the land shall prostrate themselves all day, and whoever comes, too, and in the evening they shall close it.
Tze'enah Ure'enah
“They will bow” [46:3]. The people should bow on the Sabbath and New Moon before God. From here we learn that it is a great mitzvah to bow when one comes into the synagogue. This is compared to bowing in the Temple. Each synagogue is compared to the Temple.
