'Children's' in the Bible

So the household overseer and the city supervisor, along with the elders and the children's guardians, sent word to Jehu, telling him, "We will serve you and do everything you ask. We won't set up a king, so do what you want to do."

but he did not execute the children of the murderers, in keeping with what is written in the Book of the Law of Moses, as the LORD had commanded: "Fathers must not be put to death because of their children's sin; nor are children to die because of their fathers' sin, for each person is to be put to death for his own sin."
