'How Long' in the Bible

And Moses and Aaron went in to Pharaoh, and said to him, Thus says LORD, the God of the Hebrews, How long will thou refuse to humble thyself before me? Let my people go, that they may serve me.

And Pharaoh's servants said to him, How long shall this man be a snare to us? Let the men go, that they may serve LORD their God. Do thou not yet know that Egypt is destroyed?

And LORD said to Moses, How long do ye refuse to keep my commandments and my laws?
