The Philistine arose, and came and drew nigh Like a stalking mountain. Having nothing but victory in his thoughts, he marched in a stately manner, pompously covered over with armour, and fearing nothing. But David, being loaded with no armour, ran nimbly toward him, so far was he from fear! David smote the Philistine in his forehead Which was bare, perhaps the proud giant contemning David so much as to neglect to pull down his helmet over his face, lifting up that part of it which covered his forehead; or else the stone was thrown with such force that it pierced the helmet first, and then the forehead, or went in at the place that was left open for his eyes. However it was, the divine hand directed it. And he fell upon his face to the earth “See,” says Henry, “how frail and uncertain life is, even then when it thinks itself best fortified, and how quickly, how easily, and with how small a matter, the passage may be opened for life to go out and death to enter. Goliath himself has not power over the spirit to retain the spirit, Ecclesiastes 8:8: let not the strong man glory in his strength, nor the armed man in his armour. See how God resists the proud, and pours contempt upon those that bid defiance to him and his people! None ever hardened his heart against God and prospered.”
