'Perhaps' in the Bible

But the Israelis responded to the Hivites, "Perhaps you live in our midst. If this is so, how can we make a treaty with you?"

Now then, give me that hill country about which the LORD spoke back on that day, because you yourself heard back then that the Anakim were there, with great reinforced cities. Perhaps the LORD will be with me and I will expel them, just as the LORD said."
