Scholars identify three different roots אהל ('hl) in the Bible, whose meanings don't seem to have a lot to do with each other:
The Hebrew root אהל ('hl I) is part of a Semitic root-cluster that contains Arabic and Assyrian words meaning to be inhabited or settlement, city and even bed. In the Bible occurs one important noun derived from this root, and a verb derived from the noun:
- The masculine noun אהל ('ohel), meaning either tent (Song or Solomon 1:5, Jeremiah 6:3), or general dwelling or habitation (Psalm 91:10, Isaiah 16:5). In the majority of occurrences of this noun, it refers to the tabernacle: the Tent of the Meeting (Exodus 33:7, Numbers 12:5).
- The denominative verb derived from the previous noun: אהל ('ahal), meaning to pitch a tent. This verb occurs only in Genesis 13:12 and 18 and Isaiah 13:20.
A peculiar different verb, which is spelled identical to the verb that means to pitch a tent, is אהל (ahal II), meaning to be clear, shine as used only in Job 25:5, where Bildad says, "If even the moon has no brightness [ . . . ] in His sight".
Apparently, the form אהל ('ahl) is also the parent of a masculine noun אהל ('ahal), denoting sweet smelling aloes (Proverbs 7:17, Psalm 45:9), or associated trees (Numbers 24:6).
