The Hebrew verb kalal means to complete, to make perfect, or to bring to full measure. It describes the state of wholeness and flawless completeness, used of beauty in Ezekiel and of the perfection that belongs to God alone.
In the Old Testament, kalal and its derivatives describe the pinnacle of beauty and completion. The word carries both aesthetic and moral dimensions — a completed thing is perfect in form and purpose. Ezekiel uses it to describe Tyre's beauty and the pride that came with it (Ezekiel 27:4), while the concept points toward the ultimate perfection of God's purposes. Scripture consistently reminds us that only God achieves true kalal; human attempts at perfection lead to pride, while divine completeness leads to worship.
