Targum Jonathan on Genesis
But after Jakob had gone, the shepherds went to the well, but found no water; and they waited three days, if that it might (again) overflow; but it overflowed not; and then came they to Laban on the third day, and he knew that Jakob had fled; because through his righteousness it had flowed twenty years.
Targum Jerusalem
And it was, when the shepherds were gathered together, they sought to water the flock, but were not able; and they waited two and three days, if that the well might overflow; but it overflowed not; and then came they to Laban in the third day, because Jakob had fled.
