'Perhaps' in the Bible

Ahab said to Obadiah, "Go through the land, to all the springs of water, and to all the brooks. Perhaps we may find grass and save the horses and mules alive, that we not lose all the animals."

It happened at noon, that Elijah mocked them, and said, "Cry aloud; for he is a god. Either he is musing, or he has gone aside, or he is on a journey, or perhaps he sleeps and must be awakened."
