'Peradventure' in the Bible

Wherefore ye shall make images of your tumors, and images of your mice that mar the land; and ye shall give glory unto the God of Israel: peradventure he will lighten his hand from off you, and from off your gods, and from off your land.

And he said unto him, Behold now, there is in this city a man of God, and he is a man that is held in honor; all that he saith cometh surely to pass: now let us go thither; peradventure he can tell us concerning our journey whereon we go.
