H “eyes” = ophthalmos. From optanomai (to appear, be seen by); from horao (become, seem, appear). This is eye or sight. It is used figuratively for the mind’s eye, a vision, or for envy.
I “opened” = dianoigo. 8x in NT. From dia (through, because of, across, thoroughly) + anoigo (to open or open up in a literal or figurative sense; to speak freely); {from ana (up, back, again, among, between, anew) + oigo (to open)}. This is to open fully. It can mean to open the womb as a firstborn does or figuratively to explain or expound.
J “recognized” = epiginosko. From epi (on, upon, what is fitting) + ginosko (to know, recognize, realize, perceive, learn; gaining knowledge through personal experience). This is to perceive, discern, acknowledge, recognize, know exactly because of direct interaction.
K “vanished from…sight” = aphantos + ginomai. Aphantos is 1x in NT. From a (not, without) + phaino (to bring light, cause to appear, shine, become visible or clear). Literally, not appearing, so this is invisible, hidden, or vanished. Ginomai is the same as {untranslated} in v30. See note A above.
