'Perhaps' in the Bible

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

It happened at noon that Elijah mocked them and said, "Call out with a loud voice, for he [is] a god! Perhaps he is meditating, or {is using the bathroom}, or [is] on a journey. Perhaps he [is] asleep and must wake up!"

Then his servants said to him, "Please now, we have heard that the kings of the house of Israel are kings of mercy. Let us now put sackcloth on around our waists and ropes on our heads. Then let us go out to the king of Israel. Perhaps {he will let you live}."
