'Perhaps' in the Bible

Now, please go, curse this people for me because they [are] stronger than me; perhaps I will be able to strike them and drive them out from the land because I know whoever you bless [is] blessed, and whoever you cursed is cursed."

'Look! A people went out from Egypt. Look! They cover {the surface of the land}. Now, go, curse them for me. Perhaps I will be able to attack them and drive them out."

And Balaam said to Balak, "Station yourself at your burnt offering, and I will go; perhaps Yahweh will come to meet me, and whatever he shows me I will tell to you." So he went [to] a barren height.

Then Balak said to Balaam, "Please, come, I will take you to another place; perhaps {it will be acceptable to} God, and you will curse for me from there."
