These few examples of archaeology are encouraging as the Bible is indeed supported by many cases like these, along with historical accounts and fulfilled prophecies coming to pass. But please remember that it is not needed to validate the Word of God as given by inspiration of God. Before these secondary and external evidences were found the Bible was still true. If it weren't for the Cylinders of Nabonidus perhaps historians would still be scoffing at Daniel chapter 5, but obviously the word of God abides forever.
THE CYLINDERS OF NABONIDUS
Daniel 5:29 - Then commanded Belshazzar, and they clothed Daniel with scarlet, and put a chain of gold about his neck, and made a proclamation concerning him, that he should be the third ruler in the kingdom.
Notice the words 'that he should be the third ruler in the kingdom'. Historians who were sceptics of God's Word used to scoff at this because it used to be claimed that there was only one ruler, not two. Not only that, historians thought that Nabonidus was the last king of Babylon, and Daniel 5 tells us that Belshazzar was the last king of Babylon when the Persians overthrew the city in 539 B.C.
Why is it no longer mocked? Because they made new discoveries. The Cylinders of Nabonidus was discovered in the 19th century. It describes Belshazzar (Balthazar) as Nabonidus' eldest son. I quote from this Wikipedia article, that Nabonidus (the biblical name is Nebuchadnezzar) 'often left rule to his son Belshazzar'. This is what Daniel 5 tells us. Nebuchadnezzar, the king of the Babylon dynasty, ruled with his son, Belshazzar.
Daniel 5:11 - There is a man in thy kingdom, in whom is the spirit of the holy gods; and in the days of thy father light and understanding and wisdom, like the wisdom of the gods, was found in him; whom the king Nebuchadnezzar thy father, the king, I say, thy father, made master of the magicians, astrologers, Chaldeans, and soothsayers;
THE CYRUS CYLINDER
It dates to the 6th century BC. The Cylinder's text has traditionally been seen by biblical scholars as corroborative evidence of Cyrus' policy of the repatriation of the Jewish people following their Babylonian captivity (an act that the Book of Ezra attributes to Cyrus), as the text refers to the restoration of cult sanctuaries and repatriation of deported peoples.
THE MERNEPTAH STELE
It dates from the 13th century BC. The Ancient Egyptian Merneptah Stele has inscriptions written by Merneptah (the successor to Ramesses the Great who is the pharaoh from the book of Exodus) that speak of Israel.
THE SARGON STELE
It dates from the 8th century BC. Sargon the king of Assyria is mentioned in Isaiah 20:1.
THE MESHE STELE
It is also known as the Moabite Stone, and dates from the 9th century BC. It refers to Israel, gives an account similar to that given in 2 Kings 3:4–8 and is the earliest extra-biblical reference to the God of Israel.
