"שויתי ה׳ לנגדי תמיד" ("I have placed God before me constantly", Ps. 16:8) is cited in Rama (OC 1:1) as support for what he writes there: that one should be aware that he's always before God, who can see all his actions, including when he's alone at home or in bed.
Many synagogues have this verse quoted on their walls. I've don't recall ever seeing it, however, in any other religious-run establishment, such as a home, or a retail shop, or a classroom, or an office, or….
Is there a source that specifically connects the verse, especially a Ramaesque interpretation thereof, to synagogue-type activities (Torah study and/or prayer, I guess)?
