Mishnah Berurah — משנה ברורה

Passage of the Binding - Before the passages of the offerings. One may say the passage of the Binding and the passage of the Manna even on Shabbat. It's not enough to just read them, but one should contemplate what he's saying and recognize the wonders of Hashem. And so too what is written in the Talmud: "Anyone who recites: 'A Psalm of David' (Psalms 145) three times every day is assured of a place in the World-to-Come" (Berakhot 4b:17) - it is in the same vein. And the reason for reciting all these is: [regarding] the passage of the Binding, it is in order to recall the merit of our forefathers every day, and in order to subdue one's evil inclination, just as Yitzchak [was willing to] give up his life; [regarding] the passage of the Manna, it is in order that one should believe that all his sustenance comes through [Hashem's] personal supervision, as it is written [regarding the Manna]: "the one who had taken more had no extra, and the one who had taken less, was not lacking" (Exodus 16:18) - to show that excessive effort [on a person's part, for the sake of his livelihood] is of no use. And see in [Talmud] Yerushalmi, [Tractate] Berachot: "Anyone who recites the passage of the Manna, he is guaranteed that his sustenance will not be diminished."; [regarding] the passage of the Ten Commandments, it is in order that one should recall the revelation on Mount Sinai every day and strengthen his belief in Hashem; [regarding] the passages of the offerings, [it is based on] what is written in [Tractate] Menachot: "'This is the law of the sin offering' (Leviticus 6:18)... [this teaches that] anyone who engages in [studying] the law of the sin offering [is ascribed credit] as though he sacrificed a sin offering..." (Menachot 110a:13).
