A — 1: δύναμις
(Strong's #1411 — Noun Feminine — dunamis — doo'-nam-is )

"power," (a) used relatively, denotes "inherent ability, capability, ability to perform anything," e.g., Matthew 25:15 , "ability;" Acts 3:12 , "power;" 2—Thessalonians 1:7 , RV, "(angels) of His power" (AV, "mighty"); Hebrews 11:11 , RV, "power" (AV, "strength"); see ABILITY; (b) used absolutely, denotes (1) "power to work, to carry something into effect," e.g., Luke 24:49; (2) "power in action," e.g., Romans 1:16; 1—Corinthians 1:18; it is translated "might" in the AV of Ephesians 1:21 (RV, "power"); so Ephesians 3:16; Colossians 1:11 (1st clause); 2—Peter 2:11; in Romans 15:19 , AV, this noun is rendered "mighty;" RV, "(in the) power of signs." The RV consistently avoids the rendering "might" for dunamis; the usual rendering is "power." Under this heading comes the rendering "mighty works," e.g., Matthew 7:22 , RV (AV, "wonderful works"); 11:20-23; singular number in Mark 6:5; in Matthew 14:2; Mark 6:14 the RV has "powers;" in 2—Corinthians 12:12 , RV, "mighty works" (AV, "mighty deeds"). See MIRACLE , especially POWER.
