Charles Ellicott Commentary Exodus 12:32

"Take both your flocks and your herds, as ye have said, and be gone; and bless me also." — Exodus 12:32 (ASV)

And bless me also. —Here Pharaoh’s humiliation reaches its extreme point. He is reduced by the terrible calamity of the last plague not only to grant all the demands made of him freely, and without restriction, but to crave the favor of a blessing from those whom he had despised, rebuked (Exodus 5:4), thwarted, and finally driven from his presence under the threat of death (Exodus 10:28). Those who controlled the outcomes of life and death must, he felt, have the power to bless or curse effectively.
