John Calvin Commentary Genesis 32:13

"And he lodged there that night, and took of that which he had with him a present for Esau his brother:" — Genesis 32:13 (ASV)

And took of that which came to his hand. In endeavoring to appease his brother with presents, he does not act distrustfully, as if he doubted whether he would be safe under God's protection. This, indeed, is a fault too common among people: that when they have prayed to God, they turn here and there and contrive futile evasions for themselves; whereas the principal advantage of prayer is to wait for the Lord in silence and quietness.

But the holy man’s intention was not to make himself busy and anxious, as if he were discontented with the sole help of God. For although he was certainly convinced that God being favorable toward him would alone be sufficient, he still did not neglect to use the means that were in his power, while leaving the outcome in God's hand.

For though by prayer we cast our cares upon God, so that we may have peaceful and tranquil minds, this security should not make us lazy. The Lord desires that all the resources He provides us be put to use. But the diligence of the pious differs greatly from the restless activity of the world; because the world, relying on its own efforts and independent of God's blessing, does not consider what is right or lawful. Moreover, it is always in anxiety, and by its frantic activity, it only increases its own inner turmoil.

The pious, however, hoping for the success of their work to come only from God's mercy, apply their minds to finding means for this sole reason: that they may not bury God's gifts through their own lethargy. When they have done their part, they still depend on the same grace of God; and when nothing more remains that they can attempt, they are nonetheless at rest.
