How do the motifs of night and day point up the meaning of the passage?

Judges 6:25–27 describe Gideon’s actions, and they are framed with references to night: That night the Lord said to him (Judges 6:25) and but because he was too afraid of his family and the men of the town to do it by day, he did it by night (Judges 6:27). Judges 6:28–32 describes the struggle of the men of Ophrah against Gideon, and they are framed with references to the daytime: “When the men of the town rose early in the morning” (Judges 6:28) and whoever contends for him shall be put to death by morning…. Therefore on that day Gideon was called Jerubbaal (Judges 6:31–32). Assis explains: These motifs combine well with the meaning of the passage. Gideon fears the men of the city; he is apparently beset by doubts, and therefore acts at night. On the other hand, the men of Ophrah act resolutely and confidently; accordingly their acts are carried out in the context of the 'day' motif. The men of Ophrah react forcibly to the destruction of the Baal, but in the second part Gideon is completely passive in face of their rage. The men of Ophrah accuse him, and demand that his father bring him out to be killed, and in the entire relation of this act, no reaction is heard from Gideon. Gideon’s failure to react in the daytime reflects his internal state, and he acts at night.¹
