1 Samuel 8:3
"But his sons did not walk in his ways; they were inclined to pursue dishonest profit, they accepted bribes and they perverted justice."
Although Samuel entrusted his sons to help him judge, 1 Samuel 8:3 tells us that his sons did not follow his good example. This shows us that even a very faithful person can do their best and be a great parent, but their children can still decide to follow a different course. Samuel set a good example in that he didn't allow his sons bad ways to alter his own course.
