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!

9-11. The privileges of the first-born which belonged to Joseph (1Ch 5:1, 2) were assigned to Ephraim by Jacob (Ge 48:1). The supremacy of the tribe thus intimated was recognized by its position (in the marching of the nation to Canaan) next to the ark (Nu 2:18-24), by the selection of the first permanent locality for the ark within its borders at Shiloh, and by the extensive and fertile province given for its possession. Traces of this prominence remained after the schism under Rehoboam, in the use, by later writers, of Ephraim for Israel (compare Ho 5:3-14; 11:3-12). Though a strong, well-armed tribe, and, from an early period, emulous and haughty (compare Jos 17:14; Jud 8:1-3; 2Sa 19:41), it appears, in this place, that it had rather led the rest in cowardice than courage; and had incurred God's displeasure, because, diffident of His promise, though often heretofore fulfilled, it had failed as a leader to carry out the terms of the covenant, by not driving out the heathen (Ex 23:24; De 31:16; 2Ki 17:15).
