James 3:1 My brethren, let not many of you become teachers, knowing that we shall receive a stricter judgment.
James 3:1 我的弟兄们，不要多人作师傅，因为晓得我们要受更重的判断。
Supposed there's a teacher, who, out of carelessness on rare occasion taught his students that a cow has 5 stomachs. Consequently, One of the students became a teacher and, based on his past notes, taught his students that a cow has 5 stomachs.
Who is at fault here?
The first teacher, second teacher, both teachers or no one?
[@more@]Both. Those who teach must be responsible at what they teach.
