Merism
Pair of opposites signifying totality
Two contrasting items used together to mean everything between. "Heavens and earth" means "all creation."
"In the beginning God created the heavens and the earth." Hebrew has no single word for "the universe" — so it uses a pair of opposites to mean the whole. Heaven AND earth = everything between, including everything. This figure of speech is called merism, and it's all over the Bible: "young and old" (everyone), "going out and coming in" (your whole life), "by day or by night" (always). Recognizing merism keeps you from misreading the parts as exhaustive lists when they're really shorthand for the totality.
- Gen 1:1 "Heavens and earth" — all creation.
- Hos 11:9 "I am God and not man" — divine vs. human, the two categories.
- Hos 14:9 "The righteous … the rebellious" — all people.
- Ps 139:8 "If I ascend to heaven … if I make my bed in Sheol" — total inescapability.
