Genesis 29:1-3

1Then Jacob hurried on, finally arriving in the land of the east.

2He saw a well in the distance. Three flocks of sheep and goats lay in an open field beside it, waiting to be watered. But a heavy stone covered the mouth of the well.

3It was the custom there to wait for all the flocks to arrive before removing the stone and watering the animals. Afterward the stone would be placed back over the mouth of the well.
