'Saying' in the Bible

Now in the first year of Cyrus, king of Persia, in order that the word of the Lord given by the mouth of Jeremiah might come true, the spirit of Cyrus, king of Persia, was moved by the Lord, so that he made a public statement through all his kingdom, and put it in writing, saying,

And they gave praise to the Lord, answering one another in their songs and saying, For he is good, for his mercy to Israel is eternal. And all the people gave a great cry of joy, when they gave praise to the Lord, because the base of the Lord's house was put in place.

Then the king sent an answer to Rehum, the chief ruler, and Shimshai the scribe, and their friends living in Samaria, and to the rest of those across the river, saying, Peace to you:

They sent him a letter saying, To Darius the king, all peace:

And they made answer to us, saying, We are the servants of the God of heaven and earth, and we are building the house which was put up in times long past and was designed and made complete by a great king of Israel.

Which you gave to your servants the prophets, saying, The land into which you are going, to take it for a heritage, is an unclean land, because of the evil lives of the peoples of the land and their disgusting ways, which have made the land unclean from end to end.
