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 9:21

9:21 yes, while I was still praying, ²  the man Gabriel, whom I had seen previously ³  in a vision, was approaching me in my state of extreme weariness, ⁴  around the time of the evening offering.

[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?”

[9:21]  ² tn Heb “speaking in prayer.”

[9:21]  ³ tn Heb “in the beginning.”

[9:21]  ⁴ tn The Hebrew expression בִּיעָף מֻעָף (mu’af bi’af) is very difficult. The issue is whether the verb derives from עוּף (’uf, “to fly”) or from יָעַף (ya’af, “to be weary”). Many ancient versions and modern commentators take the first of these possibilities and understand the reference to be to the swift flight of the angel Gabriel in his coming to Daniel. The words more likely refer to the extreme weariness, not of the angel, but of Daniel. Cf. 7:28; 8:27; 10:8-9, 16-17; also NASB.
