The rare word ul denotes bodily strength, the body itself, or specifically the belly or womb as the seat of vitality and strength. Its connection to physical power and generative capacity links it to concepts of life-force and vitality in ancient Hebrew thought.
Hebrew anthropology, unlike Greek dualism, viewed the body as integral to the whole person. Strength (ul) was not separate from spirituality — the body was the temple of the living God. The belly as the seat of strength connects to related concepts like the "loins" as the source of future generations (one's offspring would "come from the loins"). This holistic view of embodied existence foreshadows New Testament theology, where the resurrection of the body — not just the immortality of the soul — is the hope of the believer.
