Excute - Vine's Expository Dictionary of New Testament Words
Excute[ 1,,G4160, poieo ]
to do, to make," is thrice rendered "execute," of the Lord's authority and acts in "executing" judgment,
(a) of His authority as the One to whom judgment is committed, John 5:27;
(b) of the judgment which He will mete out to all transgressors at His Second Advent, Jude 1:15;
(c) of the carrying out of His Word (not "work," as in the AV) in the earth, especially regarding the nation of Israel, the mass being rejected, the remnant saved, Romans 9:28. That He will "execute His Word finishing and cutting it short," is expressive of the summary and decisive character of His action. See DO.
