'Perhaps' in the Bible

He said to him, "See now, there is in this city a man of God, and he is a man who is held in honor. All that he says comes surely to pass. Now let us go there. Perhaps he can tell us concerning our journey whereon we go."

How much more, if perhaps the people had eaten freely today of the spoil of their enemies which they found? For now has there been no great slaughter among the Philistines."
