A New Beginning
Moses here proclaims another of God’s mercies, that, having redeemed His people, He was their constant leader and guide; as the Prophet also in the Psalms distinctly makes reference to both. (Ps. 77:15; and 78:14.) It was indeed a marvellous act of loving-kindness that, accommodating Himself to their ignorance, He familiarly presented Himself before their eyes. He might, indeed, have protected them in some other way from the heat of the sun, and directed them in the darkness of the night; but, in order that His power might be more manifest, He chose to add also His visible presence, to remove all room for doubt.
As to his saying that God always appeared to them, that they might march by night as well as by day, he does not mean that they went on continually without any rest, since he had just before mentioned that their first station was in Succoth, from whence they encamped in Etham, but merely informs us that the flow of God’s grace was continual, since the token of His favour and protection shone forth no less amidst the darkness of the night than at mid-day itself.
