אָדַשׁ
to tread out (grain)
Definition
The Hebrew verb אָדַשׁ (ʼâdash) means to thresh or tread out grain, specifically the process of separating edible grain from its husks by treading or beating. It describes the agricultural practice of using animals or human feet to crush harvested stalks on a threshing floor. In its single biblical occurrence in Isaiah 28:28, it is used metaphorically to describe God's careful, measured discipline of His people, contrasting it with the thorough crushing of grain. The word carries the sense of a deliberate, controlled action rather than random destruction.
Biblical Usage
This verb is used only once in the Old Testament, in Isaiah 28:28. It appears in an agricultural metaphor where God compares His judgment to the process of threshing different grains. The context is a prophecy about God's dealings with Israel, using farming imagery to explain that His discipline is measured and purposeful, not endless or destructive. The usage is poetic and illustrative, drawing from common Israelite life to convey a spiritual truth.
Etymology
אָדַשׁ is a primitive root verb in Hebrew, meaning it is not derived from another Hebrew word. It is specifically related to the process of threshing grain. Cognates exist in other Semitic languages, such as Ugaritic and Akkadian, with similar meanings related to treading or threshing. The root conveys the idea of pressing or trampling to separate valuable material from waste.
Semantic Range
Though used only once, אָדַשׁ is theologically significant in Isaiah 28:28 as it illustrates God's wisdom in judgment. The metaphor teaches that God's discipline of His people is not arbitrary or overly harsh, but purposeful and carefully calibrated, like a farmer who knows exactly how to thresh each type of grain. Understanding this Hebrew term enriches the reading by highlighting the contrast between mere punishment and redemptive correction, emphasizing God's patient wisdom even in times of hardship.
In ancient Israelite culture, threshing was a vital agricultural step after harvest. Grain was spread on a hard, open threshing floor, and oxen or other animals would tread over it, or farmers would use a threshing sledge, to separate the kernels from the chaff. Isaiah's audience would immediately understand the imagery: different grains (like caraway or cumin versus wheat) required different levels of force. This cultural knowledge makes the metaphor in Isaiah 28:28 powerful, showing God's tailored approach to discipline.
דּוּשׁ (dûsh, H1758) — a more common general verb for threshing, often with a sledge. זָרָה (zârâh, H2219) — to winnow or scatter after threshing. חָבַט (châbaṭ, H2251) — to beat or strike off, as in beating olives from a tree.

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.
