Numbers 14:18

16 Because the Lord was not able to take this people into the land which he made an oath to give them, he sent destruction on them in the waste land.

17 So now, may my prayer come before you, and let the power of the Lord be great, as you said:

18 The Lord is slow to wrath and great in mercy, overlooking wrongdoing and evil, and will not let wrongdoers go free; sending punishment on children for the sins of their fathers, to the third and fourth generation.

19 May the sin of this people have forgiveness, in the measure of your great mercy, as you have had mercy on them from Egypt up till now.
