Chasidut zu Schoftim 9:55

Regarding wine, it is written (Judges 9:13), “my wine, that gladdens G-d and men.” This expression is puzzling: what is there about wine that “gladdens G-d”? The answer is that wine, like milk, is a metaphor for Torah, as we find in a passage referring to the Torah (Isaiah 55:1), “go buy wine and milk without money and without price.” Each of these two things represents a particular quality of Torah.
