Gud is a rare but evocative verb meaning to invade or press in upon — to come at with force and momentum. It appears in Jacob's blessing over Gad (Genesis 49:19): "Gad shall be raided [yegudennu gad] by raiders, but he shall raid at their heels." The wordplay with the name "Gad" reinforces the tribal character of relentless resilience.
Gud carries a theology of perseverance under assault. Gad is attacked but attacks back. The tribe experiences the full force of enemy invasion — yet overcomes. The image anticipates the NT call to "take hold" and press forward: Paul's athletic metaphors, the heavenly kingdom "forcefully advancing" (Matthew 11:12), and the idea that saints are more than conquerors (Romans 8:37). God's people may be pressed but are never crushed.
