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.English Standard Version
And when many evils and troubles have come upon them, this song shall confront them as a witness (for it will live unforgotten in the mouths of their offspring). For I know what they are inclined to do even today, before I have brought them into the land that I swore to give."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.
