Of the four, Goliath was the strongest and greatest. What the Scriptures tell about him is but a small fraction of what might have been told. The Scriptures refrain intentionally from expatiating upon the prowess of the miscreant. Nor do they tell how Goliath, impious as he was, dared challenge the God of Israel to combat with him, and how he tried by every means in his power to hinder the Israelites in their Divine worship. Morning and evening he would appear in the camp at the very time when the Israelites were preparing to say the Shema.
