אַרְכֻבָה
the knee
Definition
The Hebrew noun אַרְכֻבָה (ʼarkubâh) specifically refers to the knee or kneecap. It appears only once in the Old Testament in Daniel 5:6, describing how King Belshazzar's 'knees knocked together' in terror. This singular usage highlights a physical, bodily reaction to a divine encounter. The word denotes the anatomical joint, but in its biblical context, it powerfully symbolizes a loss of strength and composure in the face of God's judgment.
Biblical Usage
This word is used only in Daniel 5:6. It describes the physical effect of fear and terror upon King Belshazzar when he sees the mysterious handwriting on the wall during his feast. The context is a dramatic narrative of divine judgment against a proud monarch, where the weakening of his knees signifies his sudden vulnerability and the collapse of his royal authority.
Etymology
The word אַרְכֻבָה (ʼarkubâh) is an Aramaic loanword used in the Hebrew text of Daniel. It derives from a root corresponding to the Hebrew רָכַב (rakhav, H7392), which generally means 'to ride' or 'to mount.' The connection to the knee likely comes from the sense of bending or the joint's action, as in mounting a chariot or animal. This illustrates how body parts were often named for their function.
Semantic Range
Though used only once, this word carries significant theological weight. In Daniel 5:6, the failing of the king's knees is a direct, physical manifestation of God's sovereign judgment. It visually demonstrates the biblical theme that human power and pride are ultimately frail before the Almighty. Understanding this term enriches the reading by emphasizing that divine encounters can have tangible, bodily effects, humbling the mighty and revealing true spiritual states. In ancient Near Eastern culture, the knee was associated with strength, stability, and blessing (e.g., placing hands on knees while blessing). For a king's knees to knock together was a profound sign of terror and dishonor, indicating a complete loss of regal composure and control. This would have been a shocking image to the original audience, vividly portraying the total overthrow of a ruler's power. בֶּרֶךְ (berekh, H1290) — The more common Hebrew word for 'knee,' used in various contexts including worship (bending the knee) and blessing (Genesis 48:12).
