מוֹסָדָה
a foundation
Definition
The Hebrew noun מוֹסָדָה (môwçâdâh) refers to a foundation, base, or established support. It most often describes the physical foundations of the earth or mountains, as in poetic passages where God's power shakes the very foundations of the world (2 Samuel 22:8, Psalm 18:7). In a metaphorical sense, it can refer to the established order or principles of creation, as in Isaiah 40:21, which speaks of the 'foundations of the earth' being laid. The word also appears in a restorative context, describing the 'repairer of the breach' who restores the 'foundations' of a community in Isaiah 58:12.
Biblical Usage
This word is used exclusively in poetic and prophetic books of the Old Testament, including Deuteronomy, Samuel, Psalms, and Isaiah. Its usage is almost entirely metaphorical or cosmic, describing the foundational structures of creation or society. It frequently appears in theophanic contexts—descriptions of God's powerful appearance—where the foundations of the earth tremble (e.g., 2 Samuel 22:8, Psalm 18:7). In Deuteronomy 32:22 and Isaiah 24:18, it is used in warnings of divine judgment that reaches to the very foundations.
Etymology
The word מוֹסָדָה is the feminine form of the masculine noun מוֹסָד (môwçâd, H4144), which also means 'foundation.' Both derive from the root יָסַד (yâsad, H3245), meaning 'to found, establish, or lay a foundation.' This root conveys the act of setting something firmly in place, giving the noun its sense of a stable, established base. Cognates appear in other Semitic languages with similar meanings related to founding and establishing.
Semantic Range
This word is theologically significant as it connects God's creative power with His sovereign judgment and restorative grace. The 'foundations' represent the established order of creation, which is entirely dependent on God's sustaining power and subject to His intervention. When the foundations shake (Psalm 18:7), it signifies God's direct, earth-altering action in judgment or salvation. Understanding this Hebrew term enriches reading by highlighting the biblical theme that all of reality—physical, social, and moral—rests on a foundation established by God, which He alone can shake or restore.
In the ancient Near Eastern worldview, the 'foundations' of the earth or mountains were not merely geological but cosmological. They represented the stable, underpinning structures of the ordered world, often seen as pillars or bases set by the deity. This concept differs from a modern scientific understanding of planetary formation. For ancient Israelites, references to shaking these foundations evoked the terrifying and awesome possibility of the world's order collapsing back into chaos, an act only attributable to the power of Yahweh.
יְסוֹד (yesôd, H3248) — A more common synonym for 'foundation,' often used in literal construction contexts (e.g., Ezra 3:6, Haggai 2:18). שָׁת (shath, H8356) — Can mean 'foundation' or 'bottom,' but is rarer and used in specific phrases like the 'foundations' of the world in Psalm 102:25.

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.
