'How Long' in the Bible

And Moses and Aaron went in unto Pharaoh, and said unto him, Thus saith Jehovah, the God of the Hebrews, How long wilt thou refuse to humble thyself before me? let my people go, that they may serve me.

And Pharaoh's servants said unto him, How long shall this man be a snare unto us? let the men go, that they may serve Jehovah their God: knowest thou not yet that Egypt is destroyed?

And Jehovah said unto Moses, How long refuse ye to keep my commandments and my laws?
