Denotes milk in both its literal and metaphorical senses. Paul invokes the image of milk as basic nourishment contrasted with solid food to describe elementary versus mature spiritual instruction (1 Cor 3:2; Heb 5:12-13). He also appeals to the literal practice of drinking milk from one's flock as a right of pastoral workers (1 Cor 9:7). Peter uses the metaphor positively, urging believers to crave pure spiritual milk for growth (1 Pet 2:2). Across all four target languages — Spanish 'leche,' French 'lait,' German 'Milch' — the single word covers both the physical substance and the metaphor.
