Albert Barnes Commentary Matthew 9:8

"But when the multitudes saw it, they were afraid, and glorified God, who had given such authority unto men." — Matthew 9:8 (ASV)

They glorified God. (See Barnes on Matthew 5:16).

To glorify God, here, means to praise him, or to acknowledge his power. The expression, which had given such power to men, was a part of their praise. It expresses no sentiment of the evangelist about the nature of Christ, but is a record of their feelings and their praise.
