The Hebrew verb giyach means to burst forth or break out — like water gushing from a spring, a child breaking forth from the womb, or a force suddenly erupting.
Giyach is used for the moment of birth when a child bursts forth from the womb (Psalm 22:9 — 'you brought me out of the womb'), and for water gushing out of the earth. This word captures the irresistible, sudden, life-giving power of God at work. The Spirit of God is associated with this kind of sudden outpouring — breaking through barriers and bursting forth with new life. It anticipates Pentecost, where the Spirit burst forth upon the disciples like a rushing wind.
