'Long' in the Bible

I told her, "You will remain with me a long time, you won't be promiscuous, you won't be involved with any man, and I'll do the same."

Likewise, the people of Israel will dwell a long time without a king, without a prince, without sacrifice, without sacred pillars, and with neither ephod nor teraphim.

Your calf, Samaria, has been thrown away. My anger is burning against them. How long until they become pure again?
