34 When He killed them, then they sought Him, And returned and searched diligently for God ; 35 And they remembered that God was their rock , And the Most High God their Redeemer . 36 But they deceived Him with their mouth And lied to Him with their tongue . 37 For their heart was not steadfast toward Him, Nor were they faithful in His covenant . 38 But He, being compassionate , forgave their iniquity and did not destroy them; And often He restrained His anger And did not arouse all His wrath . 39 Thus He remembered that they were but flesh , A wind that passes and does not return .

40 How often they rebelled against Him in the wilderness And grieved Him in the desert ! 41 Again and again they tempted God , And pained the Holy One of Israel . 42 They did not remember His power , The day when He redeemed them from the adversary ,

Matthew Henry's Commentary on Psalm 78:34-42

Commentary on Psalm 78:9-39

(Read Psalm 78:9-39)

Sin dispirits men, and takes away the heart. Forgetfulness of God's works is the cause of disobedience to his laws. This narrative relates a struggle between God's goodness and man's badness. The Lord hears all our murmurings and distrusts, and is much displeased. Those that will not believe the power of God's mercy, shall feel the fire of his indignation. Those cannot be said to trust in God's salvation as their happiness at last, who can not trust his providence in the way to it. To all that by faith and prayer, ask, seek, and knock, these doors of heaven shall at any time be opened; and our distrust of God is a great aggravation of our sins. He expressed his resentment of their provocation; not in denying what they sinfully lusted after, but in granting it to them. Lust is contented with nothing. Those that indulge their lust, will never be estranged from it. Those hearts are hard indeed, that will neither be melted by the mercies of the Lord, nor broken by his judgments. Those that sin still, must expect to be in trouble still. And the reason why we live with so little comfort, and to so little purpose, is, because we do not live by faith. Under these rebukes they professed repentance, but they were not sincere, for they were not constant. In Israel's history we have a picture of our own hearts and lives. God's patience, and warnings, and mercies, imbolden them to harden their hearts against his word. And the history of kingdoms is much the same. Judgments and mercies have been little attended to, until the measure of their sins has been full. And higher advantages have not kept churches from declining from the commandments of God. Even true believers recollect, that for many a year they abused the kindness of Providence. When they come to heaven, how will they admire the Lord's patience and mercy in bringing them to his kingdom!

Commentary on Psalm 78:40-55.

(Read Psalm 78:40-55.)

Let not those that receive mercy from God, be thereby made bold to sin, for the mercies they receive will hasten its punishment; yet let not those who are under Divine rebukes for sin, be discouraged from repentance. The Holy One of Israel will do what is most for his own glory, and what is most for their good. Their forgetting former favours, led them to limit God for the future. God made his own people to go forth like sheep; and guided them in the wilderness, as a shepherd his flock, with all care and tenderness. Thus the true Joshua, even Jesus, brings his church out of the wilderness; but no earthly Canaan, no worldly advantages, should make us forget that the church is in the wilderness while in this world, and that there remaineth a far more glorious rest for the people of God.
