John Calvin's Bible Commentary
Psalms 105:39
39.He spread out a cloud for a covering The Psalmist enumerates certain miracles by which God continued his grace towards his people in the wilderness. This order is worthy of notice; for it was no small confirmation which was added to that incomparable work of redemption, when God ceased not to show himself the guide of their journey. Accordingly, after they had passed through the Red Sea, he spread a cloud over them by day to protect them from the heat of the sun; and during the night, he gave them light by a pillar of fire, that even in the midst of the darkness they might have a bright token of his presence. This continued display of his goodness was surely an unquestionable proof of his perpetual love, an open demonstration that he had adopted the children of Abraham, to foster them under his protection even to the end. What follows concerning quails, is introduced for a different purpose than that for which reference is made to the same fact in Psalms 78:26. In that passage, God’s bringing in an abundance of quails is ascribed rather to his wrath than to his beneficence, that the people might satiate the flesh; and we have seen in the exposition of that place, that this is mentioned as a matter of reproach to them. But in the text before us, passing over their ingratitude, the prophet celebrates the unremitting exercise of the divine loving-kindness towards them. Some, however, may be rather inclined to take the word ask in a bad sense, because the people besought not God with humility, (235) but through their impatience proceeded at once to murmuring, or rather arrogantly spake against him. Thus taken, the passage, by way of amplification, would mean that God, departing from his own right, humoured even their unhallowed lust. As, however, their fault is not here mentioned, let us rest in that meaning which is the most simple, namely, that the blessings by which God ratified the redemption which he had wrought are here clustered together. It next follows, that they were filled with the bread of heaven This appellation, as we have seen elsewhere, is given to the manna by way of eminence. The natural way in which the food which we eat is obtained is from the ground; but God then opened his hand more widely to the Jews, and fed them even from heaven. As it was not enough for them to be refreshed with food when they were hungry, unless they were also supplied with drink, it is added, that the rock was opened, and that the waters flowed from it through the dry places, or the desert.
