To repair a breach, examine for damage, or restore what is broken. Used specifically of the repair of the temple in 2 Kings and 2 Chronicles, and figuratively of examining for defects.
The verb badaq appears in the context of temple repair under Joash (2 Kings 12). Money collected at the temple door was given to workmen to repair the 'breaches' (bedeq) of the house. This carries deep theological weight: the state of God's house reflects the spiritual state of the covenant community. A neglected temple signals neglected covenant; a repaired temple signals renewed devotion. Amos speaks of God repairing 'David's fallen shelter' (Amos 9:11), and Paul describes the church as God's building (1 Corinthians 3:10–15).
