Apparently, in Berachos 28b there is wordage that relates to a phrase I saw in a Shul...."Know Before Whom Thou Standest." >From my understanding, of late, this phrase, this quote comes from the Talmud, Berachos 28b. I wanted to see the exact text that states this phrase. I want to understand this quote in its entirety. Does it, in fact, from you knowledge come from this reference? And what does it mean? Thank you.
Yes. The Gemara there quotes Rebbi Eliezer's final words of advice to his disciples before he died. You can see the exact text by going to

The words, "De'u Lifnei Mi Atem Omdim," are on the 25th line from the top. The straightforward meaning of this statement is that one should be constantly aware and fully focused, while standing before G-d in prayer, that one is indeed speaking to Him.
