1 Samuel 17:49
And David put his hand in his bag, and took there a stone, and slang it, and smote the Philistine in his forehead…
A short time ago a geologist heard of a builder's yard where an enormous heap of stones might be purchased. The man of science bought the whole stock for a few pounds, and had the collection removed to his own premises. From the heap the geologist was able to discover many unique specimens of fossils, and today several of our leading museums have been enriched and smaller museums supplied with collections worth in all a large sum. Common weapons in the hand of a good man are often used by the Lord to achieve victory. God can use the simplest gifts of His workers if consecrated to His service.
Parallel VersesKJV: And David put his hand in his bag, and took thence a stone, and slang it, and smote the Philistine in his forehead, that the stone sunk into his forehead; and he fell upon his face to the earth.
