Under prophecy we may understand an utterance, through divine ecstasy or compulsion (1 Samuel 10:10.; Amos 3:8; Isaiah 8:11; Jeremiah 1:7; Jeremiah 20:9). Dreams, although belittled by Jeremiah (Jeremiah 23:28), and visions were frequent means of divine revelation: cp. Dreams, Genesis 20:3; Genesis 28:12; Genesis 37:5; Genesis 37:9; Visions Isaiah 6:1; Amos 7:1; Amos 7:4; Amos 7:7; Amos 8:1; Jeremiah 1:11; Ezekiel 1:1., etc. Since young men are dreamers and old men seers, it may be implied that youth shall have the knowledge of age and age the enthusiasm of youth.

Blood, and fire, and pillars of smoke] indications of warfare are the wonders in the earth.

31. Eclipses are the wonders in the heavens: cp. Amos 8:9; Isaiah 13:10; Ezekiel 3:27; Matthew 24:29; Luke 21:10.
