Charles Spurgeon Commentary Genesis 32:13-16

"And he lodged there that night, and took of that which he had with him a present for Esau his brother: two hundred she-goats and twenty he-goats, two hundred ewes and twenty rams, thirty milch camels and their colts, forty cows and ten bulls, twenty she-asses and ten foals. And he delivered them into the hand of his servants, every drove by itself, and said unto his servants, Pass over before me, and put a space betwixt drove and drove." — Genesis 32:13-16 (ASV)

And he lodged there that same night; and took of that which came to his hand a present for Esau his brother; two hundred she goats, twenty he goats, two hundred ewes, and twenty rams, thirty milch camels with their colts, forty kine, and ten bulls, twenty she asses, and ten foals. And he delivered them into the hand of his servants, every drove by themselves; and said to his servants, Pass over before me, and put a space between drove and drove.

That also was a very sensible arrangement on Jacob's part, so that his brother might have time to think how he should act, for angry men often do in a hurry what they would not do if they had a little time given them for consideration. Jacob knows this, so he lets Esau's anger have an opportunity to cool down while he watches drove following drove.
