1 Samuel 17:7

The shaft of his spear was like a weaver’s beam, and its iron point weighed six hundred shekels. In addition, his shield bearer went before him.

Note 600 shekels is approximately 15.1 pounds or 6.8 kilograms.

And the staff of his spear was like a weaver’s beam; and his spear’s head weighed six hundred shekels of iron: and one bearing a shield went before him.

The staff of his spear was like a weaver’s beam; and his spear’s head weighed six hundred shekels of iron. His shield bearer went before him.

Note A shekel is about 10 grams or about 0.35 ounces, so 600 shekels is about 6 kilograms or about 13 pounds.

And the staff of his spear was like a weaver’s beam; and his spear’s head weighed six hundred shekels of iron: and his shield-bearer went before him.
