According to John Welch, since the Day of Atonement and the Feast of Tabernacles fell at or around the same time in ancient Israel, it is possible to see influences from both of these holy days upon Benjamin's speech. . . . In Mosiah 4:16 we find Benjamin declaring to the people:
And also, ye yourselves will succor those that stand in need of your succor; ye will administer of your substance unto him that standeth in need; and ye will not suffer that the beggar putteth up his petition to your in vain, and turn him out to perish. (Mosiah 4:16)
According to John Welch, giving gifts to the poor was also an important part of the Day of Atonement. "It is customary to send gifts to the poor, and a duty to ask forgiveness from one another and to appease each other." Benjamin's exhortations about giving liberally to the poor, reconciling with your neighbor, and realizing that we are "all beggars" (Mosiah 4:13-28) would be especially pertinent messages at a Day of Atonement celebration, where "restitution to man must precede sacrificial expiation from God." This, along with prayer, was a necessary condition of obtaining remission of sins ("calling on the name of the Lord daily," and imparting of your substance, "for the sake of retaining a remission of your sins from day to day"--Mosiah 4:11,26).
