Daniel 2:49 - Joseph Benson’s Commentary on the Old and New Testaments

Then Daniel requested of the king, and he set Shadrach, &c. He used his interest for his friends, as became a good man, and procured places in the government for them, that they might be assisting to him in his office, and sharers in his honour, by whose intercessions, united with his own, so important a secret had been revealed to him: such a grateful sense had he even of that service! This preferring of them would not only be a great help to Daniel in his place and business, but would afford them many and great opportunities of being useful to their brethren in captivity. But Daniel sat in the gate of the king Was a constant attendant at the king's court: and as the expression may probably signify, was a kind of chief justice, hearing and determining such causes as were brought before him, and administering justice to the people.
