'Began' in the Bible

Now it came about in the four hundred and eightieth year after the sons of Israel came out of the land of Egypt, in the fourth year of Solomon’s reign over Israel, in the month of Ziv which is the second month, that he began to build the house of the Lord.

So in the twentieth year of Jeroboam the king of Israel, Asa began to reign as king of Judah.
