is used (1) of the natural instrument, 1 Corinthians 14:8; (2) of the supernatural accompaniment of Divine interpositions, (a) at Sinai, Hebrews 12:19; (b) of the acts of angels at the Second Advent of Christ, Matthew 24:31; (c) of their acts in the period of Divine judgments preceding this, Revelation 8:2,6,13; 9:14; (d) of a summons to John to the presence of God, Revelation 1:10; 4:1; (e) of the act of the Lord in raising from the dead the saints who have fallen asleep and changing the bodies of those who are living, at the Rapture of all to meet Him in the air, 1 Corinthians 15:52 , where "the last trump" is a military allusion, familiar to Greek readers, and has no connection with the series in Revelation 8:6 to 11:15; there is a possible allusion to Numbers 10:2-6 , with reference to the same event, 1 Thessalonians 4:16 , "the (lit., a) trump of God" (the absence of the article suggests the meaning "a trumpet such as is used in God's service").
"to sound a trumpet," Matthew 6:2; as in (2) (c) above, Revelation 8:6-8,10,12,13; 9:1,13; 10:7; 11:15; as in (2) (e) 1 Corinthians 15:52 .
