Ambrose of Milan, on Isa 66:12

“For thus saith the Lord: Behold I will bring upon her as it were a river of peace, and as an overflowing torrent the glory of the Gentiles, which you shall suck; you shall be carried at the breasts, and upon the knees they shall caress you.”

“So, then, the Holy Spirit is the river, and the abundant river, which according to the Hebrews flowed from Jesus in the lands, as we have received it prophesied by the mouth of Isaiah. This is the great river that flows always and never fails. And not only a river but also one of the copious stream and overflowing greatness, as also David said, "The stream of the river makes glad the city of God."”
