King James Version
And it shall come to pass, when many evils and troubles are befallen them, that this song shall testify against them as a witness; for it shall not be forgotten out of the mouths of their seed: for I know their imagination which they go about, even now, before I have brought them into the land which I sware.New International Version
And when many disasters and difficulties come upon them, this song will testify against them, because it will not be forgotten by their descendants. I know what they are disposed to do, even before I bring them into the land I promised them on oath."Catholic Public Domain Version
And after many evils and afflictions have overwhelmed them, this canticle will answer them as a testimony; it shall never pass into oblivion, away from the mouths of their offspring. For I know their thoughts and what they are about to do today, even before I lead them into the land which I have promised to them.
