1: δύναμαι
(Strong's #1410 — Verb — dunamai — doo'-nam-ahee )

"to be able, have power," whether by personal ability, permission, or opportunity, is sometimes rendered "may" or "might," e.g., Matthew 26:9; Mark 14:5; Acts 17:19; 1—Thessalonians 2:6 . In the following the RV substitutes "can," "canst," "couldst," for the AV, e.g., Matthew 26:42; Mark 4:32; 14:7; Luke 16:2; Acts 24:11; 25:11; 27:12; 1—Corinthians 7:21; 14:31 (here the alteration is especially important, as not permission for all to prophesy, but ability to do so, is the meaning); Ephesians 3:4 . In the following the RV substitutes the verb "to be able," Acts 19:40; 24:8; Revelation 13:17 . See ABLE , B, No. 1.
