Daniel 8:16

8:16 Then I heard a human voice coming from between the banks of the Ulai. It called out, “Gabriel, ¹  enable this person to understand the vision.”

Daniel 12:8

12:8 I heard, but I did not understand. So I said, “Sir, ²  what will happen after these things?”

[8:16]  ¹ sn The only angels whose names are given in the OT are Gabriel (Dan 8:16; 9:21; cf. Luke 1:19, 26) and Michael (Dan 10:13, 21; 12:1; cf. Jude 9; Rev 12:7). The name Gabriel means in Hebrew “man of God,” and Michael means “who is like God?”

[12:8]  ² tn Heb “my lord,” a title of polite address.
