Saul and the Israel mob heard that big man’s words, and they got frightened and confused. (We have not yet translated 17:12-14. Those verses say that 3 of David’s big brothers were in that Israel soldier mob with Saul.)
While they talked, that big man from Gath, Goliath, he went out into the middle as before. And he went around and shouted out loud, as he always did. And David heard him talk like that.
You see, they already said to each other like this, “Every day, that man comes to shame us and make fun of us. But if one of our men kills him, Saul will give him big money. He will also give him his daughter to marry. And Saul will not make his family pay tax money.”
