The Hebrew noun omeq means depth, deepness, or profundity. Appearing about 5 times in the Old Testament, it refers to literal depth (of valleys) and to the overwhelming, immeasurable quality of God's wisdom and mystery.
Though omeq appears rarely, its theological impact is concentrated in Job and the Psalms, where it is used to express the unfathomable nature of God. The concept of divine depth — omeq — stands in contrast to human shallowness and the limitation of created understanding. Job 11:8 asks, 'Can you fathom the depths of God?' — declaring that God's wisdom and being exceed the deepest depths imaginable. In Isaiah 7:11, God offers a sign 'as deep as Sheol or as high as the heavens,' suggesting that His power encompasses every vertical dimension. The New Testament develops this theme in Paul's great doxology: 'Oh, the depth of the riches of the wisdom and knowledge of God! How unsearchable his judgments, and his paths beyond tracing out!' (Romans 11:33) — echoing the OT theology of divine depth.
