Psalms 107:38

What surprising changes are often made in the affairs of men! Let the present desolate state of Judea, and of other countries, explain this. If we look abroad in the world, we see many greatly increase, whose beginning was small. We see many who have thus suddenly risen, as suddenly brought to nothing. Worldly wealth is uncertain; often those who are filled with it, ere they are aware, lose it again. God has many ways of making men poor. The righteous shall rejoice. It shall fully convince all those who deny the Divine Providence. When sinners see how justly God takes away the gifts they have abused, they will not have a word to say. It is of great use to us to be fully assured of God's goodness, and duly affected with it. It is our wisdom to mind our duty, and to refer our comfort to him. A truly wise person will treasure in his heart this delightful psalm. From it, he will fully understand the weakness and wretchedness of man, and the power and loving-kindness of God, not for our merit, but for his mercy's sake.

He blesseth them also, so that they are multiplied greatly; and suffereth not their cattle to decrease. God's blessing is everything. It not only makes men happy, but it makes men themselves, by causing men to be multiplied upon the earth. When the Lord made the first pair he blessed them and said "be fruitful and multiply", and here he restores the primeval blessing. Observe that beasts as well as men fare well when God favours his people: they share with men in the goodness or severity of divine providence. Plagues and pests are warded off from the flock and the herd when the Lord means well towards a people; but when chastisement is intended, the flocks and herds rot from off the face of the earth. O that nations in the day of their prosperity would but own the gracious hand of God, for it is to his blessing that they owe their all.
