20. Behold I have received commandment to bless. He signifies that a command to bless had been given him, antl a positive law laid down for him. For, as has been said, he was not free and independent in this matter; but God had bound him to exercise the prophetic office, even against his own will. Hence he declares that it is not in his power to alter the revelation, of which he is the minister and witness. But there is a remarkable expression introduced in the midst of his declaration, viz., that God himself had blessed; whereby he intimates that the lot of men, whether adverse or prosperous, depends on the authority of God alone; and that no other commission is given to the prophets, except to promulgate what God has appointed; as if he had said, It belongs to God alone to decree what the condition of men is to be; He has chosen me to proclaim His blessing; it is not in my power either to reverse or withdraw it. Now, since Balaam here sustains the character of a true Prophet, we may gather from his words that no other power of binding or loosing is given to the ministers of the Word, except that they should faithfully bring forward what they may have received from God.
