3708 gives prominence to the discerning mind, 991 to the
particular mood or point. When the physical side recedes,
3708 denotes perception in general (as resulting principally
from vision), the prominence being in the mental element.
991 on the other hand, when the physical side recedes, gets
a purely outward sense.
4648 is more pointed than 991, often meaning "to scrutinize,
observe". When the physical sense recedes, "to fix one's
(mind's) eye on, direct one's attention to" a thing in order
to get it, or owing to interest in it, or a duty towards it.
Hence often the same as "to aim at, care for etc."
