Kol Yehudah renders a homiletic interpretation of this pasuk. Ohel, tent, implies impermanance. The ohel refers to the layman whose time allotted for Torah study is, at best, part-time. Being kovea ittim la' Torah, designating certain times during the day for the specific purpose of Torah study, is truly a praiseworthy endeavor. The individual may not necessarily become an accomplished talmid chachom, Torah scholar, but his children will.
Children emulate what they observe at home.
When they see their parents demonstrate esteem for Torah, they will follow suit. When they see that their fathers devote night or early morning to Torah study, they will have the proclivity to spend their entire day and night engrossed in limud ha'Torah. The term Yaakov refers to the lay people. This law states that one who publicly cohabits with a gentile may be slayed by kanaim, true zealots. Hashem caused Moshe to forget, so that Pinchas could react and merit the blessing he received.
