The preposition baad expresses several spatial and relational ideas: moving through or behind something; standing in the gap for another; interceding on behalf of someone. Its range includes 'through' (motion), 'for the sake of' (purpose), and 'in place of' (substitution).
The intercessory use of baad is theologically rich. When Moses prays baad Israel (Exodus 8:28–30), or when prophets are commanded to pray baad the people (Jeremiah 7:16), the preposition carries the weight of vicarious standing. The concept anticipates Christ's high-priestly intercession — standing perpetually baad his people before the Father (Hebrews 7:25). The refusal to allow Jeremiah to pray baad Israel (Jeremiah 11:14) signals the severity of divine judgment when intercession is suspended.
