To declare, make known, or show forth. This verb carries the sense of revealing what was previously hidden — whether a vision, a riddle, or divine truth. It is used especially in contexts of declaring God's works and making His righteousness known among the nations.
Chavah captures the prophetic impulse to declare what God has revealed. In the Psalms, the heavens themselves chavah — they declare God's glory (Psalm 19:2). The word implies that truth cannot be contained; it must be spoken forth. For believers, this is the call to testimony: what God has done in secret, His people are compelled to make known.
