5319 is thought to describe an external manifestation, to the
senses hence open to all, single or isolated; 601 is an
internal disclosure, to the thinking believer, and abiding. The
601 or "unveiling" precedes and produces the 5319 or
"manifestation"; the former looks toward the object revealed,
the latter toward the persons to whom the revelation is made.
Some question this explanation.
Compare: 5319, 1212

5319 - manifest, as opp. to what is concealed and invisible
1212 points rather to inner perception, 5319 to outward appearance.
