all his wonderful deeds Gideon contrasts the miracles his generation has heard about with Israel’s current situation, which to him proves God’s apathy (Psa 44:1–3, 9–16). Gideon apparently knows the real reason for Israel’s oppression—articulated by God’s prophet in Judg 6:8–10.
6:14 And Yahweh turned to him The text uses the divine name, Yahweh, meaning either that the text identifies the Angel of Yahweh (vv. 11–12) as Yahweh or that Yahweh now joins the discussion. The narrative may suggest the presence of two supernatural figures in vv. 21–23. But if the Angel of Yahweh is here identified as Yahweh, Yahweh Himself must be presumed to be invisibly present, observing the discussion but not revealed until vv. 21–23. In the case of two distinct supernatural beings (the second view), the disembodied Yahweh enters the scene here.

6:13 why. This question is central to the Book of Judges. The Angel did not answer the question, since the prophet had already answered it (vv. 8–10; Deut. 28:47–52; 29:24–27; 31:17–18). Some of the psalms ask a similar question (Ps. 44:20; 74:9–11).
6:14 Go in this might of yours. See v. 34; 7:2, 7. God would be his strength, though Gideon did not yet know it.
