“Tell them therefore, ‘Thus says the Lord Yahweh, I will make this proverb to cease, and they will no more use it as a proverb in Israel.' But say to them, ‘The days are at hand and the word (i.e. carrying out of the word - effective fulfilment) of every vision.'
Israel are to be made to realise that the proverb is now no longer true. Indeed it will cease to exist. For the opposite is about to prove true. The prophecies of Ezekiel and Jeremiah are about to come to their final awful fulfilment. And the people will see it and realise how foolish they were. ‘The days are at hand.' That is, are about to burst on them with unexpected speed.
There is a warning to us all here of the danger of assuming that the warnings of God are simply empty threats which can safely be ignored because ‘God is love', or of thinking that judgment is far off and therefore does not really matter.
