Psalms 106:31

Those that will not wait for God's counsel, shall justly be given up to their own hearts' lusts, to walk in their own counsels. An undue desire, even for lawful things, becomes sinful. God showed his displeasure for this. He filled them with uneasiness of mind, terror of conscience, and self-reproach. Many that fare deliciously every day, and whose bodies are healthful, have leanness in their souls: no love to God, no thankfulness, no appetite for the Bread of life, and then the soul must be lean. Those wretchedly forget themselves, that feast their bodies and starve their souls. Even the true believer will see abundant cause to say, It is of the Lord's mercies that I am not consumed. Often have we set up idols in our hearts, cleaved to some forbidden object; so that if a greater than Moses had not stood to turn away the anger of the Lord, we should have been destroyed. If God dealt severely with Moses for unadvised words, what do those deserve who speak many proud and wicked words? It is just in God to remove those relations that are blessings to us, when we are peevish and provoking to them, and grieve their spirits.

And that was counted unto him for righteousness unto all generations for evermore. Down to the moment when this psalm was penned the house of Phinehas was honoured in Israel. His faith had performed a valorous deed, and his righteousness was testified of the Lord, and honoured by the continuance of his family in the priesthood. He was impelled by motives that what would otherwise have been a deed of blood was justified in the sight of God; nay, more, was made the evidence that Phinehas was righteous. No personal ambition, or private revenge, or selfish passion, or even fanatical bigotry, inspired the man of God, but zeal for God, indignation at open filthiness, and true patriotism urged him on. Once again we have cause to note the mercy of God that even when his warrant was out, and actual execution was proceeding, he stayed his hand at the suit of one man: finding, as it were, an apology for his grace when justice seemed to demand immediate vengeance.
