(During a Jewish leap-year: 16 Adar II - בִּשְׁנַת הָעִיבּוּר - ט"ז אדר בּ)
[Chofetz Chaim’s note: With [the aforementioned teaching from the “Zohar”], one can explain that which the pasuk [from parshas “V’Zos HaBirachah”] says, “…‘Zivulun, be happy in your departures, and Yissachar, in your tents.’” (Divarim: 33; 18) [The] explanation [being], that even though it is not the [normal] way of a trader to be happy at the time that he goes out to [involve himself] in his trading, [he will generally] only [be happy] after his [return] to his house, [for] perhaps The Holy One, Blessed is He, will not make him successful, and his toil will [thereby be] in vain. [The above is] specifically [the case] when [one sets] sail on the ocean, [where he will not be happy, as the ocean is] a place of danger. Therefore, Moshe Rabbeinu, Alav HaShalom, said [as follows]: ‘Zivulun, you will be able to be happy when you set sail in the ship (in accordance with RaSh”I’s commentary [on the pasuk]), for Yissachar sits in your tents which you designated for him to [be involved in] Torah [study] and certification.’ Therefore, [due to your support of Yissachar’s Torah study], The Holy One, Blessed is He, will definitely bring you success, as The Holy “Zohar” said.]
 Since the tribe of Zivulun financially supported the Torah study of the tribe of Yissachar, they preceded the tribe of Yissachar in the receipt of the birachos.
 RaSh”I explains that Moshe is telling the tribe of Zivulun that they should be happy when they go out to involve themselves in trade, as they will be successful.
