2 Kings 14:7

5 And it came to pass, as soon as the kingdom was confirmed in his hand, that he slew his servants which had slain the king his father.

6 But the children of the murderers he slew not: according unto that which is written in the book of the law of Moses, wherein the LORD commanded, saying, The fathers shall not be put to death for the children, nor the children be put to death for the fathers; but every man shall be put to death for his own sin.

He slew of Edom in the valley of salt ten thousand, and took Selah by war, and called the name of it Joktheel unto this day.

8 Then Amaziah sent messengers to Jehoash, the son of Jehoahaz son of Jehu, king of Israel, saying, Come, let us look one another in the face.

9 And Jehoash the king of Israel sent to Amaziah king of Judah, saying, The thistle that was in Lebanon sent to the cedar that was in Lebanon, saying, Give thy daughter to my son to wife: and there passed by a wild beast that was in Lebanon, and trode down the thistle.

Here the Bible tells a story about someone else. Ask yourself what it can say to us today. Do read the surrounding verses too, because the context often says more than a single verse.
