Order in the Blessing of 'Me-ein Shalosh'
Question
If one needs to recite the 'Me-ein Shalosh' blessing for grain products, fruit of the tree, and fruit of the vine - what is the order in the blessing?
Answer
Shalom and joyous holidays!
First, mention 'for the sustenance', then 'for the vine', and then 'for the tree'.
This is because grain products are important, made from wheat and barley, which are first in the verse 'a land of wheat and barley'. Then comes wine, which is also important and has its own blessing, and is mentioned in the third place in the aforementioned verse. Then come the rest of the fruits of the seven species, which are not as important as the first ones, and are mentioned in the blessing under a general term.
