Māzeh (מָזֶה) means exhausted, lean, sucked dry, wasted. From māzāh (to suck out, to drain). Describes physical depletion.
Isaiah 17:4: 'In that day the glory of Jacob will fade; the fat of his body will waste away.' Israel's coming judgment is described in terms of physical wasting — the nation's prosperity and strength drained away. This is the consequence of persistent unfaithfulness. Sin is spiritually emaciated — it promises fullness but delivers depletion. Psalm 106:15: 'He gave them what they asked for, but sent a wasting disease upon them.' Getting what we want apart from God leads to māzeh — a soul sucked dry.
