Albert Barnes Commentary Daniel 5:13

"Then was Daniel brought in before the king. The king spake and said unto Daniel, Art thou that Daniel, who art of the children of the captivity of Judah, whom the king my father brought out of Judah?" — Daniel 5:13 (ASV)

Then was Daniel brought in before the king - From this it is clear that he lived in Babylon, though in comparative obscurity. It would seem to be not improbable that he was still known to the queen-mother, who, perhaps, kept up an acquaintance with him on account of his former services.

Art thou that Daniel - This is a clear proof that Belshazzar was not acquainted personally with him. See the note at [Daniel 5:11].

Which art of the children of the captivity of Judah - Belonging to those of Judah, or those Jews who were made captives, and who reside in Babylon. See the notes at [Daniel 1:3]. He could not be ignorant that there were Jews in his kingdom, though he was not personally acquainted with Daniel.

Whom the king my father - Margin, as in [Daniel 5:2], [Daniel 5:1], “grandfather.”

Brought out of Jewry? - Out of Judea. See [Daniel 1:1–3].
