On which Yesod does the Kohen pour the blood?
Why does the Torah repeat "el Y'sod Mizbach ha'Olah"?
Ramban: It is the way of the Torah to repeat things when it could have mentioned them briefly. 1
See for example, above, Pasuk 4 (Ramban). Despite that, Chazal do make D'rashos from the repeated words - for 'the Torah of Hashem is complete; It contains nothing extra; nor is there anything missing (Ramban).
