John Wesley on Genesis 29:2

Providence brought him to the very field where his uncle's flock's were to be watered, and there he met with Rachel that was to be his wife. The Divine Providence is to be acknowledged in all the little circumstances which concur to make a journey or other undertaking comfortable and successful. If, when we are at a loss, we meet with those seasonably that can direct us; if we meet with a disaster, and those are at hand that will help us; we must not say it was by chance, but it was by providence: our ways are ways of pleasantness, if we continually acknowledge God in them. The stone on the well's mouth was either to secure their property in it, for water was scarce, to save the well from receiving damage from the heat of the sun, or to prevent the lambs of the flock from being drowned in it.
