Adam Clarke's Bible Commentary Verse 1. God blessed Noah] Even the increase of families, which appears to depend on merely natural means, and sometimes fortuitous circumstances, is all of God. It is by his power and wisdom that the human being is formed, and it is by his providence alone that man is supported and preserved.
Matthew Henry Commentary
Verses 1-3 - The blessing of God is the cause of our doing well. On him we depend to him we should be thankful. Let us not forget the advantage an pleasure we have from the labour of beasts, and which their fles affords. Nor ought we to be less thankful for the security we enjo from the savage and hurtful beasts, through the fear of man which God has fixed deep in them. We see the fulfilment of this promise ever day, and on every side. This grant of the animals for food full warrants the use of them, but not the abuse of them by gluttony, stil less by cruelty. We ought not to pain them needlessly whilst they live nor when we take away their lives.
