This adverb means 'on high' or 'upward,' appearing in Habakkuk 3:10 in a theophanic vision of God's coming. The prophet describes cosmic upheaval: 'The mountains saw you and writhed; the raging waters swept on; the deep gave its voice; it lifted its hands on high.' The phrase captures the dramatic image of the ocean depths raising hands upward, perhaps in worship or terror or both. The theophany depicts all creation responding to God's appearance—mountains, waters, and the deep itself react. 'On high' emphasizes the vertical dimension of the gesture, hands reaching toward heaven in acknowledgment of divine presence.
