A — 3: Ἐφημερία (Strong'S #2183 — Noun Feminine — ephemeria — ef-ay-mer-ee'-ah )

In the NT it is used in  Luke 1:5,8 .

"a wheel," is translated "wheel" in  James 3:6 , RV, with metaphorical reference to the round of human activity (AV, "course"), as a glowing axle would set on fire the whole wooden wheel.

B — 1: Χωρέω (Strong'S #5562 — Verb — choreo — kho-reh'-o )

"to make room for, to go forward," is rendered "hath not free course," in  John 8:37 , RV (AV, "hath no place"). See Come , No. 24.
