'Peradventure' in the Bible

Come now therefore, I pray thee, curse me this people; for they are too mighty for me: peradventure I shall prevail, that we may smite them, and that I may drive them out of the land; for I know that he whom thou blessest is blessed, and he whom thou cursest is cursed.

Behold, the people that is come out of Egypt, it covereth the face of the earth: now, come curse me them; peradventure I shall be able to fight against them, and shall drive them out.
