John Calvin Commentary Matthew 8:9

"For I also am a man under authority, having under myself soldiers: and I say to this one, Go, and he goeth; and to another, Come, and he cometh; and to my servant, Do this, and he doeth it." — Matthew 8:9 (ASV)

For I am a man subject to the power of another. This comparison does not imply equality between the two cases, but is taken from the less to the greater. He forms a higher conception of the divine power, which is manifested in Christ, than of the authority which was possessed by himself over servants and soldiers.
