'Vengeance' in the Bible

So the sun stood still, and the moon stopped,Until the nation [of Israel] took vengeance upon their enemies.Is it not written in the Book of Jashar? So the sun stood still in the middle of the sky and was in no hurry to go down for about a whole day.

If we have built an altar for ourselves to turn away from following the Lord, or if [we did so] to offer a burnt offering or grain offering on it, or if to offer sacrifices of peace offerings on it, may the Lord Himself require it [of us and hold us responsible].
