Jacob reprimanded the shepherds who were sitting idly by the well: “Water the sheep and go graze them.” The shepherds explained that they could not move the boulder that covered the well until all the shepherds came (Genesis 29:7-8).
Couldn’t Jacob see that there was a huge boulder on the well? Why did he reprimand the shepherds? Perhaps they had tried to move it but couldn’t?!
Granted, but why weren’t they trying again?
Just because you did not succeed at something is no reason to give up. Try again, and again, and again.
