'Defeats' in the Bible

If he [is] able to fight with me and he defeats me, then we will be your servants; but if I prevail over him and defeat him, then you will be our servants and you will serve us."

And the men of Israel said, "Did you see this man who has come up? For he [is] going up to defy Israel! It will be [that] the man who defeats him, the king will make him very rich with great wealth and will give him his daughter [in marriage] and will make his father's house free in Israel."

Now David had spoken to the men [who were] standing with him, saying, "What will be done for the man who defeats this Philistine and removes [the] disgrace from Israel? For who [is] this uncircumcised Philistine that he defies the battle lines of the living God?"

And the troops had spoken to him according to this word, saying, "So it will be done for the man who defeats him."
