I am full of the fury... — The prophet feels himself filled, frail vessel as he is, with the righteous wrath of Jehovah. It will not be controlled.
I will pour it out. — Better, as the command coming from the mouth of Jehovah, Pour it out. The words that follow describe the several stages of man’s life, upon all of which that torrent of wrath is to flow forth — the children abroad, i.e., playing in the streets (as in Zechariah 8:5); the assembly, or gathering of young men, whether in their natural mirth (Jeremiah 15:17) or for secret plans (Proverbs 15:22); the husband and wife in full maturity; the “aged,” i.e., the elder, still active as well as venerable; lastly, the man “full of days,” whose time is nearly over and his sand run out.
