John 8:12

^A “Jesus” = Iesous. From Hebrew Yehoshua (Joshua, the Lord is salvation); {from YHVH (proper name of the God of Israel; the self-existent and eternal one); {from havah (to become) or from hayah (to come to pass, become, be)} + yasha (to deliver, defend, help, preserve, rescue; properly, to be open, wide or free, which implies being safe. So, in a causative sense, this is to free someone)}. This is Jesus or Joshua in Greek – the Lord saves or the Lord is salvation.
^B “light” = phos. From phao (to shine or make visible, especially with rays of light); from the same as phaino (to bring light, cause to appear, shine, become visible or clear). This is light, a source of light, fire, or radiance. This is light with specific reference to what it reveals. It is luminousness whether natural or artificial, abstract or concrete, literal or figurative.
^C “world” = kosmos. Perhaps from the base of komizo (to carry, convey, recover); from komeo (to take care of). This is order, the world, the universe, including its inhabitants. Literally, this is something that is ordered so it can refer to all creation. It can also refer to decoration in the sense that something is better ordered and, thus, made more beautiful. This is where “cosmos” and “cosmetics” come from.

^D “follows” = akoloutheo. From a (with, fellowship, union) + keleuthos (road, way). This is to accompany or follow someone, especially the way a disciple does.
^E “walk” = peripateo. From peri (about, concerning, around, encompassing) + pateo (to read, trample on; to trample literally or figuratively); {from patos (trodden) OR from paio (to strike, smite, sting; a hit like a single blow)}. This is to walk. Going from Hebrew figurative language, to walk referred to how you conducted your life, how you chose to live. This word is most literally walking around. Figuratively, it is living, behaving, following, how you occupy yourself. This is where “peripatetic” comes from.
^F “darkness” = skotia. 16x in NT. From skotos (darkness literal or figurative – as moral or spiritual darkness, sin and what comes from it; obscurity); from skia (shadow, thick darkness, outline; figurative for a spiritual situation that is good or bad). This is darkness or dimness. Figuratively, it can be a spiritual darkness. This is obscurity in a literal or figurative sense.
^G “life” = zoe. From zao (to live, be alive). This is life including the vitality of humans, plants, and animals – it is life physical and spiritual and life everlasting.
