Ezekiel 12:23

Tell them therefore, Thus saith the Lord GOD; I will make this proverb to cease, and they shall no more use it as a proverb in Israel; but say unto them, The days are at hand, and the effect of every vision.

The days are at hand, and the effect of every vision - "the effect," literally, the word, namely, fulfilled;

i.e., the effective fulfillment of whatever the prophets have spoken is at hand.
