Course - Vine's Expository Dictionary of New Testament Words
Course
[ A-1,Noun,G165, aion ]an age" (See AGE), is sometimes wrongly spoken of as a "dispensation," which does not mean a period of time, but a mode of dealing. It is translated "course" in Ephesians 2:2, "the course of this world," i.e., the cycle or present round of things. See AGE, ETERNAL, EVER, WORLD.
[ A-2,Noun,G1408, dromos ]
properly, "a running, a race" (from edramon, "to run"), hence, metaphorically, denotes "a career, course of occupation, or of life," viewed in a special aspect, Acts 13:25; Acts 20:24; 2 Timothy 4:7.
[ A-3,Noun,G2183, ephemeria ]
primarily, "daily service," as, e.g., in the Sept. of 2 Chronicles 13:11 (from epi, "upon, or by," hemera, "a day," Eng., "ephemeral"), hence denoted a "class," or "course," into which the priests were divided for the daily service in the Temple, each "class" serving for seven days (See 1 Chronicles 9:25). In the NT it is used in Luke 1:5, Luke 1:8.
Note: Cp. ephemeros, "daily (food)," James 2:15.
[ A-4,Noun,G5164, trochos ]
"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,Verb,G5562, choreo ]
"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.
