What does Genesis 29:8 mean?
Jacob has just learned several things at once. His journey has brought him near his destination of Haran and the household of his uncle Laban (Genesis 28:1–2). According to the shepherds standing around a well, Laban is in good health, and his daughter is approaching with a flock of sheep (Genesis 29:5–6).In the previous verse, Jacob seems to have taken some borrowed ownership of the situation around the well. He ordered the shepherds gathered with their flocks to water the sheep and get back to the pasture. This seems like a brash statement from a stranger, so perhaps the other men were being rude to Jacob. Or, he's simply trying to assert himself in an effort to win over Rachel.
Here, the shepherds respond that Jacob's plan is not how they do things. They wait until all of the sheep have arrived, all of the flocks, then they roll away the well's heavy stone covering and water all of the flocks at once. It's not clear exactly why they do it this way. Some commentators suggest, however, that the first flocks to arrive would usually be the first to be watered. Laban won't follow that practice in the following verses.
