C. F. Keil and Franz Delitzsch on Daniel 5:10

Dan 5:10

By מלכּתא interpreters rightly understand the mother of the reigning king, the widow of his father Nebuchadnezzar, since according to Dan 5:2. The wives of the king were present at the festival, and the queen came before the king as only a mother could do. Among the Israelites also the mother of the reigning king was held in high respect; cf. 1Ki 15:13; 2Ki 24:12, 2Ki 24:15; Jer 13:18; Jer 29:2. מלּין לקבל, by reason of the words, not: because of the affair, to which neither the plur. מלּי nor the gen. רברבנוהי agrees. Instead of the Kethiv עללת the Keri has עלּת, the later form. The queen-mother begins in an assuring manner, since she can give an advice which is fitted to allay the embarrassment.
