In their straits they called upon Jehovah The verbs are here in the past tense, and according to grammarians, represent a continued action. The meaning therefore is, that those who are wandering in desert places are often pinched with hunger and thirst in consequence of finding no place in which to lodge; and who, when all hope of deliverance fails them, then cry unto God. Doubtless, God grants deliverance to many when in straits, even though they do not present their supplications to Him for aid; and hence it was not so much the design of the prophet in this passage to extol the faith of the pious, who call upon God with all their heart, as to describe the common feelings of humanity. There may be not a few whose hope does not center on God, who, nevertheless, are constrained, by some invisible disposition of mind, to come to Him, when under the pressure of dire necessity. And this is the plan which God sometimes pursues, in order to extort from such persons the acknowledgement that deliverance is to be sought for from no other quarter than from Himself alone; and even the ungodly, who, while living voluptuously, scoff at Him, he constrains, in spite of themselves, to invoke his name. It has been customary in all ages for heathens, who look upon religion as a fable, when compelled by stern necessity, to call upon God for help. Did they do so in jest? By no means; it was by a secret natural instinct that they were led to reverence God's name, which formerly they held in derision. The Spirit of God, therefore, in my opinion, here narrates what frequently takes place, namely, that persons destitute of piety and faith, and who have no desire to have any thing to do with God, if placed in perilous circumstances, are constrained by natural instinct, and without any proper conception of what they are doing, to call on the name of God. Since it is only in dubious and desperate cases that they betake themselves to God, this acknowledgement which they make of their helplessness is a palpable proof of their stupidity, that in the season of peace and tranquillity they neglect him, so much are they then under the intoxicating influence of their own prosperity; and notwithstanding that the germ of piety is planted in their hearts, they nevertheless never dream of learning wisdom, unless when driven by the dint of adversity; I mean, to learn the wisdom of acknowledging that there is a God in heaven who directs every event. It is unnecessary to allude here to the sarcastic retort of the ancient buffoon, who, on entering a temple, and beholding a number of tablets which several merchants had suspended there as memorials of their having escaped shipwreck, through the kind interposition of the gods, smartly and facetiously remarked, "But the deaths of those who have been drowned are not enumerated, the number of which is innumerable." Perhaps he might have some just cause for scoffing in this manner at such idols. But even if a hundredfold more were drowned in the sea than safely reach the harbour, this does not in the least degree detract from the glory of the goodness of God, who, while he is merciful, is at the same time also just, so that the dispensing of the one does not interfere with the exercise of the other. The same observation applies to travelers that stray from the path, and wander up and down in the desert. If many of them perish for hunger and thirst, if many are devoured by wild animals, if many die from cold, these are nothing else than so many tokens of the judgments of God, which he designs for our consideration. From which we infer that the same thing would happen to all men, were it not the will of God to save a portion of them; and thus interposing as a judge between them, he preserves some for the sake of showing his mercy, and pours out his judgments upon others to declare his justice. The prophet, therefore, very properly adds, that by the hand of God they were led into the right way, where they may find a suitable place for lodging; and consequently he exhorts them to render thanks to God for this manifestation of his goodness. And with the view of enhancing the loving-kindness of God, he connects his wondrous works with his mercy; as if he should say, in this kind interposition, God's grace is too manifest, either to be unperceived or unacknowledged by all; and for those who have been the subjects of such a remarkable deliverance, to remain silent regarding it, would be nothing less than an impious attempt to suppress the wonderful doings of God, an attempt equally vain with that of endeavoring to trample under their feet the light of the sun. For what else can be said of us, seeing that our natural instinct drives us to God for help, when we are in perplexity and peril; and when, after being rescued, we forthwith forget him, who will deny that his glory is, as it were, obscured by our wickedness and ingratitude?

Then they cried unto the Lord in their trouble - The language in this verse is repeated in this psalm in Psalm 107:13, Psalm 107:19, Psalm 107:28 - as if this were the main subject of the psalm, that when the people of God in different circumstances, or under various forms of trouble, call upon God, he hears them and delivers them.
And he delivered them out of their distresses - The verb from which the noun used here is derived has the idea of being "narrow, straitened, compressed." Hence, the word comes to be used in the sense of distress of any kind - as if one were pressed down, or compressed painfully in a narrow space.

Then they cried unto the Lord - When the Israelites began to pray heartily, and the eyes of all the tribes were as the eyes of one man turned unto the Lord, then he delivered them out of their distresses.

Then they cried unto the Lord in their trouble,.... To be directed in their way, and for food and drink, as travellers do when in such distress. Natural men, even the very Heathens, when in distress, will cry unto God for relief, as Jonah's mariners did, Jonah 1:5. It is a time of trouble with awakened sinners, when they are convinced of sin by the Spirit of God; when they are pricked to the heart with a sense of it; when the terrors of death and hell get hold of them; when they see themselves lost and undone, and in a wrong way, and know not what to do; when they find themselves starving and ready to perish; and then they cry, that is, pray, unto the Lord, the God of their lives, whose ears are open to their cries.
And he delivered them out of their distresses; by leading them in a right way, and by satisfying and filling their hungry souls with good things, as it is explained, Psalm 107:7.

The Lord - Hebrews. Unto Jehovah, to the true God. For the Heathens had, many of them, some knowledge of the true God.
