And they of Beth-shemesh were reaping their wheat harvest in the valley: and they lifted up their eyes, and saw the ark, and rejoiced to see it. And they of Beth-shemesh were reaping their wheat harvest in the valley: and they lifted up their eyes, and saw the ark, and rejoiced to see it.
Those of Beth-shemesh were reaping their wheat harvest in the field in the valley when they lifted up their eyes and saw the ark arriving on the cart. The cart that bore it was drawn by cows. They rejoiced to see it because they recognized its return as God's own work.
