אַ֥שְֽׁרֵי אָדָם֮ שֹׁמֵ֪עַֽ֫ לִ֥י לִשְׁקֹ֣ד עַל־דַּ֭לְתֹתַי י֤וֹם ׀ י֑וֹם לִ֝שְׁמֹ֗ר מְזוּזֹ֥ת פְּתָחָֽי׃
Happy is the man that hearkeneth to me, Watching daily at my gates, waiting at the posts of my doors.
Rashi on Proverbs
by my doors [to be the] first to enter into the study hall and the synagogue and [the] last to leave.
