This day will the Lord deliver thee into my hand He speaks with as much assurance as Goliath had done, but upon better grounds, confiding, not in his own strength, but in the divine omnipotence, and expecting, through it, certain victory, not only over Goliath, but over the whole army of the Philistines. That all the earth may know that there is a God in Israel Superior to all others. Hebrew, That God is for Israel, or on Israel's side, and against you. Or, that Israel hath a God, a God indeed! one who is able to help them; and not such an impotent idol as you serve.

46 This day will the LORD deliverl thee into mine hand; and I will smite thee, and take thine head from thee; and I will give the carcases of the host of the Philistines this day unto the fowls of the air, and to the wild beasts of the earth; that all the earth may know that there is a God in Israel.
