Asaph is speaking on behalf of the people of Israel. He begins in verse 8 to speak of the way God settled Israel in their land as if God were a man who cleared ground and planted a grapevine. The image of the grapevine continues through verse 16.
The writer speaks of Yahweh acting favorably towards them as if Yahweh's face shone a light on them. See how you translated this in [Psalms 80:3](../080/003.md). Alternate translation: "act favorably towards us" (See: [[rc://en/ta/man/translate/figs-metaphor]])
