Kabbalah do Izajasza 49:3

This verse has been explained as follows. A person should not enter the synagogue unless he first consulted Abraham, Issac and Jacob. Because they have prepared and instituted the prayer to the Holy One, blessed be He. As it is written, "I will come into Your house in the multitude of Your love" refers to Abraham, (Chesed); "I will bow down towards Your holy temple" refers to Issac; "in the fear of You" refers to Jacob (Tiferet). Therefore, he should include himself with them and then enter the synagogue and recite his prayers. Then the scripture reads, "And He said to me, you are My servant, Yisrael, in whom I will be glorified" (Isaiah 49:3).
