Daf Yomi - Sukkah 39 - Recital of Blessings

The Gemora rules that all brochos should be recited before one performs the mitzva. The Tashbatz comments that it is evident from the language of the Gemora that the brocha should be recited immediately prior to the performance of the mitzva and not some time beforehand. This is apparent from the fact that the Gemora used the word ‘over l’assiyoson’ and not ‘kodem l’assiyoson.’
