What is the magical significance for the 23rd psalm and the Lords prayer in hoodoo? I see people beginning and ending their prayers with these ones and I don't know why. I also hear people using psalm 23 as an all purpose one.
Often times, people use it as an all-purpose prayer because it boils down to "the Lord will provide". So whatever you're paying about, whether you need something or somebody else does, be that strength or a new bike, the Lord has your back. This is actually used in some practices as a way to honor whatever your higher power is, be that the Christian god, Hecate, or the Great Horned One. Since hoodoo is a very personalized and adaptable practice a lot of people borrow scripture from any number of other paths.
