'Four' in the Bible

Four men with a skin disease were at the entrance to the gate. They said to each other, “Why just sit here until we die?

Nevertheless, the Lord said to Jehu, “Because you have done well in carrying out what is right in My sight and have done to the house of Ahab all that was in My heart, four generations of your sons will sit on the throne of Israel.”

The word of the Lord that He spoke to Jehu was, “Four generations of your sons will sit on the throne of Israel,” and it was so.
