'Defy' in the Bible

And the men of Israel said, Have ye seen this man that comes up? for to defy Israel is he come up: and it shall be, that the man who smites him, him will the king enrich with great riches, and will give him his daughter, and make his father's house free in Israel.

And David spoke to the men that stood by him, saying, What shall be done to the man that smites this Philistine, and takes away the reproach from Israel? for who is this uncircumcised Philistine, that he should defy the armies of the living God?
