קַו
a cord (as connecting), especially formeasuring; figuratively, a rule; also a rim, a musical string or accord
Definition
The Hebrew noun קַו (qav) primarily refers to a measuring line or cord, used for construction and surveying, as seen in the description of the bronze sea in 1 Kings 7:23. Figuratively, it denotes a standard, rule, or principle of justice, such as the 'line of justice' and the 'plumb line of righteousness' in Isaiah 28:17. It can also represent a boundary or limit, as in Job 38:5 where God asks who stretched the measuring line over the earth. In poetic contexts, it is used for a musical string (as in the concept of a 'line' going out through all the earth in Psalm 19:4) and for a rim or circular band.
Biblical Usage
The word appears 14 times, primarily in poetic and prophetic books. Its literal use for a builder's measuring line is found in descriptions of temple objects (1 Kings 7:23, 2 Chronicles 4:2). Its figurative use for a standard of judgment is prominent in Isaiah (Isaiah 28:10, 13, 17) and 2 Kings 21:13. The poetic usage extends to cosmology in Job 38:5 and divine communication in Psalm 19:4.
Etymology
Derived from the root קָוָה (qavah, H6960), meaning 'to wait for' or 'to look for,' with an underlying sense of tension or stretching. This root connection suggests the idea of a cord being drawn tight. The noun form קַו specifically denotes the cord or line itself, used for measuring, marking boundaries, or creating tension, as in a musical string.
Semantic Range
This word is theologically significant as it connects God's creative order with His moral standards. The measuring line symbolizes divine precision in creation (Job 38:5) and the establishment of justice (Isaiah 28:17). It portrays God as the master builder and righteous judge who sets boundaries and standards. Understanding this Hebrew term enriches the reading of passages about God's faithfulness, judgment, and the order inherent in His world, moving from physical measurement to spiritual principle.
In ancient Israel, a measuring line (qav) was a common tool for builders, surveyors, and craftsmen, typically a cord marked at intervals. This tangible object made the metaphorical uses for divine judgment and cosmic order highly relatable. The concept of a 'plumb line' (a weighted cord) for testing vertical truth was a powerful image for moral and spiritual alignment, as used by the prophets.
חֶבֶל (chevel, H2256) — a thicker rope or territory, often for measuring land. פְּתִיל (pethil, H6616) — a thread or cord, usually finer. מִדָּה (middah, H4060) — a measurement or dimension, the result of using a qav.

How this works
Hebrew definitions are from Brown-Driver-Briggs (1906) and Strong's Exhaustive Concordance (1890), both public domain. BDB was groundbreaking for its era but reflects 19th-century assumptions about Semitic etymology. Modern scholarship (HALOT, DCH) has revised many entries. Use these definitions as a starting point for exploration, not as the final word on a term's meaning in context.
