Targum for Numbers 24:23

And he took up the parable of his prophecy, and said, Woe to them who are alive at the time when the Word of the Lord shall be revealed, to give the good reward to the righteous, and to take vengeance on the wicked, to smite the nations and the kings, and bring these things upon them!

Woe to him who is alive when the Word of the Lord setteth Himself to give the good reward to the just, and to take vengeance on the wicked!
