The Hebrew kavod (H3519) means glory, honor, abundance, or weight. Its root (kaved) means 'heavy' — that which has substance and weightiness. The glory of God (kavod YHWH) is the manifest presence of His infinite being and holiness.
No word better captures Israel's experience of God than kavod. The kavod YHWH filled the tabernacle and temple as a pillar of cloud and fire. Ezekiel watches this glory depart from a sinful temple and return to the restored temple. The New Testament declares that this same glory 'became flesh and dwelt among us' (John 1:14) in Jesus Christ — the full and final kavod of God in human form.
