(39) Cloud.--As in Isaiah 4:5. The reason assigned for the cloud in the historical books is lost sight of. Instead of a pillar marking the line of march, or as a protection against the pursuing foe, it is a canopy for protection from the sun. Sir Walter Scott expresses the same idea in Rebecca's hymn.

Verse 39. - He spread a cloud for a covering. The "pillar of the cloud" is intended. It was a "covering" to the Israelites on the night of the passage of the Red Sea (Exodus 14:19, 20), and perhaps also to some extent in the wilderness, when it may have sheltered them from the sun's rays (Hengstenberg); but its main purpose was to direct them on their way (Exodus 14:21), to tell them when to move and when to step, and how long to stop (Exodus 40:36-38). And fire to give light in the night. By night the "pillar of the cloud" became a "pillar of fire," shedding a certain radiance around, and giving the people under all circumstances sufficient light (Exodus 13:21; Exodus 40:38).

105:24-45 As the believer commonly thrives best in his soul when under the cross; so the church also flourishes most in true holiness, and increases in number, while under persecution. Yet instruments shall be raised up for their deliverance, and plagues may be expected by persecutors. And see the special care God took of his people in the wilderness. All the benefits bestowed on Israel as a nation, were shadows of spiritual blessings with which we are blessed in Christ Jesus. Having redeemed us with his blood, restored our souls to holiness, and set us at liberty from Satan's bondage, he guides and guards us all the way. He satisfies our souls with the bread of heaven, and the water of life from the Rock of salvation, and will bring us safely to heaven. He redeems his servants from all iniquity, and purifies them unto himself, to be a peculiar people, zealous of good works.He spread a cloud for a covering,.... That is, the Lord spread one over their heads as an "umbrella", to protect them from the heat of the sun; this refers to the pillar of cloud, Exodus 13:20, though that seems to have been in an erect posture, and to go before the children of Israel to direct them in their journey, and not a covering to them. Kimchi says it was a covering to them when they rested, but not when they journeyed: but when they rested it only covered the tabernacle, not the people, for anything we read of it, Numbers 9:21, it looks as if there were more clouds than one, and indeed the Jews speak of many, and particularly make mention (e) of one that was over the heads of the Israelites, that the heat of the sun, and the hail and rain, might not have power over them; and of such use this cloud was, at least at certain times, if not always; a type of Christ, who is the covering and shelter of his people from the heat of the fiery law, of the flaming sword of justice, of the wrath of God, of the fiery darts of Satan, and of the fury of wicked men.

And fire, to give light in the night: this respects the pillar of fire which gave them light by night; an emblem of Christ, who is the light of his people, when it is a night season with them, as it sometimes is; a night of affliction and distress, of darkness and desertion, of temptation, of carnal security and sleepiness; when Christ arises as a light in darkness, and enlightens by his presence, by his Spirit, and by his word; as well as is as fire to warm, refresh, quicken, and comfort them when chill and cold, in such seasons.
