What is this Pasuk coming to teach us?
Rashi: It teaches us that one may only swear by Hashem's Name if one fears Him, serve Him and cleaves to Him.
Having already taught this in Va'eschanan 6:13, why does the Torah repeat it here?
Temurah, 3b: To teach us that it is a Mitzvah to make a Shevua'h to fulfill a Mitzvah. 1
Temurah, Ibid.: In keeping with the Pasuk in Tehilim, 119:106 "Nishba'ati Va'akayeimah Lishmor Mishp'tei Tzidkecha". See Torah Temimah, note 21. 10
Why does the Torah add "u'Vo Sidbak" here, but not in Va'eschsnan 6:13?
Refer to 6:13:151:1-5.
R. Bachye (according to Kabalah): With reference to 10:20:1.1:3 - It refers to Binah.
"u'vi'Shemo Tishave'a". Having already taught us this in Va'eschanan 6:13, why does the Torah repeat it here?
