עמק
The root עמק ('amoq) has to do with being deep, and is used in pretty much the same literal and figurative ways as our English verb to be deep is used. The verb עמק ('amoq) is mostly used in the figurative sense, either of being deep in the sense of being profound (Psalm 92:5) but mostly in the sense of being deeply hidden (Isaiah 29:15, Jeremiah 49:8), and that usually because of deep rottenness or depravity (Hosea 5:2, Isaiah 31:6).
This verb's derivations are:
- The masculine noun עמק ('emeq), a frequently occurring word meaning vale, valley or lowland (Genesis 14:17, Isaiah 22:7, Psalm 65:13).
- The masculine noun עמק ('omeq), meaning depth (Proverbs 9:18 and 25:3 only).
- The adjective עמק ('ameq), denoting the unintelligibility of foreign speech (Isaiah 33:19 and Ezekiel 3:5-6 only).
- The adjective עמק ('amoq), meaning deep in a literal sense (Leviticus 13:3, Ezekiel 23:32) or figuratively (Psalm 64:6, Job 12:22).
- The masculine plural noun מעמקים (ma'amaqqim), denoting again mostly figurative and distressing depths (Psalm 69:3, Isaiah 51:10, Ezekiel 27:34)
