chal.lon denotes a structural opening, used for looking out, opening or passing through, and describing a building’s features.

The attested noun consistently denotes a physical opening in a structure: people look through or out from it, objects and persons pass through it, and buildings are described as having such openings, sometimes shuttered or arranged around architectural features.

   The singular form occurs where Noah opens an opening in the ark in Genesis 8:6, David is lowered through one in 1 Samuel 19:12, and Rahab lowers men and fastens a cord at one in Joshua 2:15 and Joshua 2:18. Plural forms describe architectural features in 1 Kings 6:4 and Ezekiel 40:16, where the APB renders framed, shuttered openings in a house and gate complex; viewing through such an opening is also shown in Genesis 26:8.

In the Anselm Project Bible: The APB commonly presents the noun as “window” or “windows,” including “shuttered windows” in architectural descriptions. These renderings confirm the verse-level setting rather than establish a separate lexical distinction.
