Mefiboshet is crippled because he fall when Saul's descendants are running away from mass slaughter. Am I correct here?
Also when Abner is killed looks like there is more mass slaughter again.
But who would want to kill Saul's grand children? The only one with interests in their death is David and he doesn't like killing kings. I am not sure about that one.
Others have little incentive to kill Saul because David is not going to reward them anyway.
So who are killing Saul's descendants?
Not sure whether I should ask this in Christian forum (which don't care), history (which don't believe in bible), or here.
