Oneg (עֹנֶג) describes exquisite delight, luxury, or sensory pleasure. It appears only 5 times as a noun, with the related verb anog appearing more frequently. The word carries a positive sense of wholesome delight in Isaiah 58 (the Sabbath as oneg) and a warning against self-indulgent luxury in Micah 2:9 and Lamentations 4:5.
Isaiah 58:13–14 is the theological summit of oneg: 'If you call the Sabbath a delight [oneg]... then you will find your joy in the LORD.' Here God transforms the concept of pleasure itself — the highest oneg is not food, luxury, or leisure, but the LORD Himself. This anticipates Psalm 37:4 ('Delight yourself in the LORD') and points to the New Testament joy (Greek: chara) that flows from abiding in Christ. The object of our delight determines the quality of our life. True delight is Sabbath delight — rest and communion with God.
