John Chrysostom

Then he brings forward another testimony also and says, "but one in a certain place testified, saying." Wherefore did he not mention the name of the prophet, but hid it? Yea, and in other testimonies also he doth this: as when he saith, "but when He bringeth in again the First-Begotten into the world, He saith, And let all the Angels of God worship Him. And again, I will be to Him a Father. And of the Angels He saith, Who maketh His angels spirits. And, Thou, Lord, in the beginning hast laid the foundations of the earth": so also here he saith, "but one in a certain place testified, saying." And this very thing (I conceive) is the act of one that conceals himself, and shows that they were well skilled in the Scriptures; his not setting down him who uttered the testimony, but introducing it as familiar and obvious.
