'Perhaps' in the Bible

"Now as to why I've come to speak with your majesty the king, it's because the people have made me afraid, so your humble servant told herself, "I'll go speak to the king, so perhaps the king will do what his humble servant has requested.

Perhaps the king will listen and deliver his humble servant from the oppression of the man who intends to eliminate both me and my son from what God has apportioned to us!'

Perhaps the LORD will take note of my troubles and return good to me instead of curses today!"
