Boē (βοή) is the noun corresponding to the verb boaō, denoting a cry, outcry, or shout. It describes the audible expression of urgent need, alarm, or lamentation. In the one New Testament occurrence (James 5:4), it refers to the "cries" of defrauded workers reaching the ears of God — a powerful image of divine justice.
The single NT use of boē places it in the context of economic injustice: the wages withheld from laborers cry out to the Lord of Sabaoth. This echoes the blood of Abel crying from the ground (Genesis 4:10). Scripture teaches that the cries of the oppressed are heard by God — injustice does not escape the divine ear, and judgment is coming for those who exploit the vulnerable.
